30 hrs in Heaven -- Observing report Mudgee Star Party NGCLes (Pt 1)

Hi All,

Welcome to yet another instalment of the continuing adventures of Gerald – this time reporting from the 2008 Mudgee Star Party. The MSP this year ran simultaneously with the SPSP over the first weekend in April.

I apologise for the many spelling errors and typos in advance – I simply couldn’t be bothered in carefully editing this mammoth report. It may well be the longest post in the observations reports ever (If that ain’t a challenge, I don’t know what is!!).

Well I have to say that, at least observing wise this has to have been the best Mudgee Star Party I can remember for quite some time. Fortunately I got to stay four nights. Thursday night was dusk to dawn clear, Friday was interrupted by about one hours light fog a little after midnight, Saturday was dusk to dawn and Sunday was partly to mostly clear between 8.30pm till 1.30am. Realistically, you could hardly ask for better.

I left home at 11am on the Thursday under clear skies after there had been a vigorous southerly change the night before that had caused significant storm damage in Victoria. Viewing the weather forecast and the charts in the lead-up days I wasn’t entirely optimistic but it all turned out well.

First stop was Lithgow for a spot of lunch at the Shell café and then on to Mudgee arriving a bit after 3pm. The countryside around Lithgow is quite green and has evidently had quite a lot of rain lately – the dams all looked pretty full. As you drive further northward it browns-off a bit but Mudgee still looks a whole lot better than a couple of years ago. Both of John’s dams are more than ˝ full. Not staying in the shack this year (John’s neighbours are living there while they build their house) I pitched the tent in “Hornby’s Hovel” and then set up the ‘scope in the bus-parking area. This might seem a strange choice but I’ve been itching to give it a go for a year or so because while it has slightly inferior horizons in all directions (particularly east and west) it is very flat, has a pretty good northern horizon, not crowded and well sheltered from any wind.

The *exact* position for this spot is at 149 deg 29’ 34.24” E and 32 deg 37’ 57.63” S and it proved to be quite a good one. The main observing field a little southwest of this spot is a good one but a bit uneven underfoot and this year also quite crowded. Being down in the bus-park also allowed us to play some music without disturbing those who do not appreciate quality progressive rock The bus-park was also only a stones-throw from the camp site too (all down hill). Maybe the bus-park should be re-named the “Dale of the Dobs”?

I won’t try to list all who were there while I was up at Mudgee, and if I forgot to list you here, don’t take it hard. John & Patti Vetter, Chris Toohey, Peter Ward, Ken McEwen (whose C8 blew over in the wind on Thursday night), Mel Hulbert, Arthur Hall, Matt Smith, Col Shepherd, Roger Giller, Tony Austin, Craig McIntyre, Ian Walsh, Damien Clarke … and there were at least two times that number I just can’t recall at the moment.

I was set up collimated and almost everything was pretty-much ready by 4.30pm when Gary and Taylor arrived and pitched Taylor’s tent and set up the stove and table etc.

Sunset was just after 6.30pm daylight-savings time and I was itching to get going under very good skies. As it turned out the Thursday night had pretty average seeing (after that southerly – quite predictable) but the transparency was very good. I would have rated the sky as a 9/10 but this year I came armed with a new toy – a Unihedron SQM – L (Sky Quality Meter) and that provided objective evidence of the quality of the surface brightness of the sky. This is the new model with an IR blocking filter and a lens that restricts it to a reading 10 degrees wide. They are objective measurement of the sky quality.

The sound track for the Thursday night included: Guitars: Mike Oldfield, Help!: The Beatles, Paint the Sky with Stars: Enya, Animals: Pink Floyd, 12th Man Again: Twelfth Man, The Persian Hours: Tamara Cislowska, and Dark Side of the Moon: Pink Floyd.

At the start of observing the SQM read 21.70 = ZLM of +6.48 and started with some galaxies in Sextans:

These three egs appear in a line N-S from -80 to -79 to -2-25-23 overall length 20'. -80 to -78 sep is about 10', -80 has lower SB but is more elong while -78 has the better S.B. Fairly well populated field for Sextans. -78 is in PA 0 probably 1.75' x 40" fairly consistent SB and appears to have a fairly large. somewhat brighter core-zone which is 1' x 20" in the same PA, but no real nucleus.

-78 is found near a bunch of faint stars and is round, probably 1' or just over in diameter brightening broadly and slightly to the centre without noticeable core, zones or nucleus. Seems to have pretty diffuse edges.

MCG -2-25-13 is about 8' further south and is a somewhat lower S.B eg of consistent, low SB growing slightly and broadly to the axis nr centre but having no defined core zone or nucleus. Seems about 1.5' x 20".

This eg appears pretty much in PA 30, seems surprisingly bright for mag 13.6. Seems elong in PA 30 about 1.25 x 30" with a good SB halo with very faint edges and with a large oval-shaped core which is slightly brighter. On the S end of the halo on axis 1.2 to 2/3rds of the way out is a very faint mag 15.5 *Doesn’t have tips -- rounded ends . Nice for mag 13.6

This is a really attractive eg in about PA 75 with a superimposed *. Seems about 1.75 x 20" lengthened oval haze with good S.B. The super * is 1/2 way out along the halo at the W end (shown on the DSS) just above the axis, but strangely the E end of the halo seems to have a different appearance to the W end, seeming to have a diffuse VLB blob hanging off the end and that is slightly elong in PA 0 and not mirrored in the W end of the halo. Maybe due to *??. The core is not well-defined but contains a very faint *ar nucleus at threshold No other *s associated.

Pt 2 to follow ....

-66 and -69 are both very bright egs, -66 is in the centre and -69 is 7' distant in PA 75 while --65 is about 5' in PA 225. -66 and -69 are both very bright and large Egs with very good SB -66 would be maybe 2.25 x 1.75' in PA 75 with very faint edges rising broadly and mod to centre with a small, compact core zone elong in the same PA about 20" diameter that is considerably brighter than the halo and contains a brighter stellaring at centre.

-69 has a less conspicuous core/nucleus and is overall of lower SB but still elong in PA 45, 2.25' x 2 growing broadly and mod to centre from very diffuse edges and contains a considerably brighter higher SB core zone 15" diameter that is much brighter than halo.

-65 is a much smaller and fainter eg, considerably fainter, elong in about PA 160, 1' x 40" no evident core or nucleus, brightening broadly and weakly to centre.

This is a very faint and small eg took a while to pick up Seems to be weakly elong in PA 0, 40" x 30" growing azonally, weakly and broadly to the centre with a small round slightly brighter core zone at centre with no apparent nucleus. No *s associated.

This eg is quite close to a very distracting tri of mag 7, 8, & 9 *s of which the hypotenuse points straight at the eg. It seems in PA 45, good S>B 1.25' x 40" growing from indistinct edges broadly and slightly to the centre but at centre is a pretty well defined small core-zone that contains a very faint stellaring.

These two look quite strange in the field together, they both seem elong in PA 120 and both have a nearby star that is on axis -90 to the W and -16 to the E of the same brightness and at the same distance -- to that extent they look mirror-imaged. IC 590 is NE of the MCG eg and they are separated by about 10'.

-90 is elong in PA 120, about 50" x 20" with a mag 13 * to the WNW by 1.5'. Seems to have a weakly brighter broad streak through it.

-16 has a mag 13* at the opposite end about 40" x 20" with lower SB brightening weakly to the axis near centre but having no zones or apparent nucleus. Weak SB fairly faint.

This is a pretty non-descript small round eg found to the N of a faint pair mags 12 + 14 which is to the S of the eg by 10', small lowish SB 40" diameter growing broadly and slightly to centre with no evidence of zones but occasionally there is a glimpse of a faint stellaring near centre.

This eg is found to the S from a distracting mag 6* which is a bit of a pain. Seems round, mod bright considering the distraction, a bit over 1' diameter rising broadly and slightly to centre where there is a somewhat brighter round, well-defined core/nucleus.

These two egs are near a mag 8 * that is yellowish. -92 to the N by 3', -93 to the E by 5'. -92 is a very LSB diffuse haze that is only visible with AV. Difficult to establish size, maybe 1' diameter with no apparent central brightening.

-93 is a little brighter than -92, seems to be round and have better SB. Round, about 40" diameter growing slightly to the centre without core or nucleus apparent.

This is found between a mag 8*and a mag 6* close to the field stops to the E and the NW. Seems to be a fat oval elong in PA 90, maybe 1.25' x 50" grows from very diffuse edges broadly and slightly to centre azonally without core or nucleus.

Note R.V! This is a fairly small, non-descript LSB, small eg in a field which is pretty blank. To the SE about 15' away is a mag 9*. Seems to be weakly elong in PA 45, about 1' diameter, very diffuse edges, growing broadly and weakly to centre without apparent core or nucleus. With AV is occasionally seems slightly mottled or grainy.

That cleans out most of what remained in my to-do list in Sextans.

Now moving on to several showpiece galaxies on the Virgo/Coma border that I did not have observations for with the 18” under a truly dark sky. The SQ reading at this stage was 21.82 = ZLM of 6.53

These are three wonderful edge on egs -16 is in the middle of the group and is a wonderful and very bright edge on spiral eg in PA 15. Very, very elong, much the brightest, 8' x 1.25' indefinite tips to the halo, good SB halo rising in brightness to the axis nr centre. The outer halo is of quite LSB. there is a fairly small quite elong core, 40" x 10" in the same PA contained a diffuse spot-type nucleus which is not much brighter than the surrounding core. There is to the E, Immediately adjacent to the core on the E flank of the halo. a mag 14*.

South by 10' is -06 which is somewhat fainter but still mod bright eg, very very elong in PA 0. 3.5' x 20" Very faint tips and outer halo, fairly large slightly brighter core zone about 1' x 15" in the same PA only slightly brighter than the halo and no real nucleus. Occasional hint of a very faint string of stellarings nr centre where the nucleus would be. Lowish SB.

-22 is to the NE by 10' from -16 and is a very faint and very LSB streak of very LSB haze and it is close to a distracting mag 9 *has lower SB than -06, skinnier though and shorter, 2.75'x 10" in PA 45, has a very faint star at the NE tip mag 15.5 and nr centre is grows weakly and azonally to the axis but no real core zone or nucleus visible.

M100 is a very bright eg witch seems to sit in an I triangle of mag 14 *s just on the edges of the halo or slightly within. The overall SB of the halo is good without being high, generally brightens broadly and slightly to the centre. 7-8', diameter round at centre is a well defined somewhat brighter small, probably 40" diameter core coze that has a very definite edge to it brightening broadly and mod to centre within that core and a hardly brighter spot on the centre. There is a weak hint of spiral structure, Directly S of the core in the outer halo is a weak, broad arc-shaped enhancement about just over 1' long and another similar but even fainter in the NW edge of the halo in about PA 300, about a similar distance from the core.

NGC 4322 is to the N of M100 and another to the E is NGC 4326, both of which are about 6' away from centre. Small spots 30" rising broadly and weakly to centre without nucleus. Both are round -28 is slightly the brighter.

Found to the SW of a mag 6.5* which seems a yellowish and has on the E edge of the halo a mag 13 *. Really pretty face on spiral nearly 5' diameter with some structure. The core zone is nearly 1' diameter is obvious and a spiral arm in the outer halo starting in PA 180 heading W and curling out from the halo as it eventually terminates pointing N at about PA 270. Quite LSB outer halo brightening weakly to centre. Not a sharp transition to core but within the core brightens slightly to centre with a faint spot almost dead centre. Halo seems a little lop-sided so that the N side is a little more extensive. Very, very pretty.

This is a very large group of eg which is dominated by -73 and -81. 81 is the brightest, a bright oval haze about 2.5' x 1.5' in PA 90 rising broadaly and moderately to the axis near centre with a small slightly brighter core zone. -73 is to the SW by about 6'.

-73 is similar to -81 but has a slightly less surface brightness and is elong in PA 0, slightly smaller also it has a small elong slightly brighter core.

-77 is immediately E of -73 as a tiny 15" patch of faint mist with a slight brightening to centre.

-68 is to the SSW of -73 by about 5' as a small elong spindle in PA 45 about 45" x 10" growing slightly to centre where there is a small mod brighter core. Good SB overall.

-50 is W of -73 by about 8' as a tiny scrap of mist to the W of a mag 15 *.

IC 3153 is about 8' NW of -73 as a tiny, tiny scrap of extremely fiant haze with a spot in the centre.

-70 is about 9' N of -73 as a flattened oval of reasonable SB haze in PA 90, mod bright, 1.25 x 15" rising moderately to centre where there is a slightly brighter elong core.

-66 is directly N of -70 by
5' just to the S of a mag 9 * which is very very distracting. A tiny, tiny streak of weak haze in PA 90.

-82 is 10' NE of -70 as a tiny dim patch mist about 10" dia as is -87 with a 14th magnitude * at the W edge. Very tiny and faint.

NGC 4300 is 20' E of -81 as a small mod bright spindle, 1.5' x 10" in PA 45 with a small, round somewhat brighter core and overall has good SB.

And that concluded recorded observing for the night at about 2.35am with the last SQM reading I took at 2am showing 21.74 = ZLM +6.48. We continued observing until nearly 4.30am which included many winter Milky Way objects, paying attention in particular to G.Cs in Sagittarius. We also took a bit of a look at a wobbly Jupiter but the seeing wasn’t much chop and the image at x185 wasn’t that pleasing.

Climbing into bed at almost 5am I was wearing a very contented look as I snuggled down into my new goose-down sleeping bag that had me feeling warm as toast in seconds despite the fact that the temperature was hovering over 0 deg C.
___________________________________ __________________________________

We slept late the next morning and after brekky tripped into Mudgee for a bit of a walk around, a Kebab at the Kebab shop in the Wollies Mall and to pick up some perishable foods for the next few days. We took our time and wandered back at about 3pm (we forgot Peter Ward’s talk was on – D’oh) and spent the afternoon relaxing under a bright blue sky.

After an early dinner, I headed up to the bus-park and prepared everything before spending a bit of time up at the top shed enjoying happy hour, a cleansing ale and a few nibbles.

Not a cloud in sight, I re-started observing at 8.00pm but struck my only glitch for the weekend: After starting the first object, the voice recorder said it was full and refused to record further observations. A quick check showed that somehow it had been switched on to Stereo HQ sound recording and last nights 90mins worth was all it would take. So no recorded observations for the Friday night.

I took an SQM reading out of interest at about 9.30pm which showed 21.84 – WOW!!

The soundtrack for the evening included: Ummagumma: Pink Floyd, Hyperborea and Force Majeure: Tangerine Dream, Five Miles Out & Ommadawn: Mike Oldfield, and then Star’s End: David Bedford.

I spent most of the early evening in the southern sky and we had quite a few visitors drop down for a look through by my and Gary’s ‘scope. We looked at a lot of showpieces like: the Horsehead (Barnard 33 & IC 434), M42, M104, NGC 4038-39, the Eta Carinae complex (NGC 3372), the Tarantula (NGC 2070), NGC 5189, and all the globulars of the far southern sky.

IC 2531 is one of my very favourite spots in the sky, a really spectacular and faint exactly edge-on barred spiral that considering its distance, must be an extremely massive galaxy. An image is here:

http://stdatu.stsci.edu/cgi-bin/dss_...e&fov=NONE&v3=

And of course NGC 2997 (the emblem of the Sutherland Society is equally stunning and shows clear spiral arms in conditions like this. An image is here:

http://stdatu.stsci.edu/cgi-bin/dss_...e&fov=NONE&v3=

About midnight, some thin fog rolled in that lasted for about an hour and we ended up inventing a game to play with the laser-pointers that basically amounted to follow-the-leader as about 6 of us from all over the property skipped from star to star following one leader. An onlooker much have thought some LGM had landed near Mudgee!

It cleared-off about 1.30am and at about 2.30am young Damien Clarke who had been observing up top near the shed with John’s big 16” dob called “Tweety” came down and claimed that he had found something near Gamma Corvi that wasn’t on his maps. To be honest I was pretty sceptical at first and he wasn't able with any certainty to pinpoint its location. Damien went back up for a while and came back with his own 8" dob and quickly found it a short distance from Gamma Corvi.

I took a look through his 'scope and it took me completely by surprise -- it was a pretty big (maybe 8 arc-mins diameter or larger) nebulous object, probably about 10th magnitude with a weakly brighter zone/spot in the centre. Then went over to my own 18" and within seconds had it in the field and Thought I saw a weak greenish hue in the centre -- it certainly looked like a comet. The Argo Navis gave me an almost pinpoint RA and Dec and a search on Megastar with Realsky showed there was definitely no known object at that position -- certainly none that matched the appearance. I also displayed the known comets -- none. This is how it looked at x85:

A large, maybe 8-10' diameter round patch of weak milky haze rising from very indistinct edges slightly to centre where there is a small weakly brighter, about 40" diameter core-zone but no real pseudo nucleus. Inner regions seem to have a weakly lime hue.

I usually download and install the orbital elements of new comets if it looks likely to be bright and it didn't fit my additions -- excitement was building. It had to be a comet, the only question was whether it was already known.

The next step was to go to the internet to check for other known comets using the MPC data -- a visit up to the shed to log on proved a big frustration -- the net positively refused _point blank_ to connect (don't ya just love dial-up??) whatever we did.

I tried waking-up a couple of people (Gordon Garrad, Steve Quirk) that could help without success. I knew Rob McNaught wouldn’t be available (in Ilford for the SPSP), so no point making that call and with time passing on (now about 4.30am) there was only one alternative -- ring Brian Marsden at the IAU.

I made the phone call at 4.35am and gave the accurate position we had determined firstly using the Argo and refined to almost arc-second accuracy using Megastar. Silence for nearly a minute then ...

We got the same news -- Damien had re-discovered 2007 W1 -- just like you guys! Disappointment! ... but it was exciting while it lasted. We turned in about 5am again and it was still clear.

30 hrs in Heaven -- Observing report Mudgee Star Party NGCLes (Pt 5)

Pt 5 ...

The Saturday morning dawned fine and clear (no I didn’t actually see it) and after a spot of brekky, I had to solve the problem of my voice recorder. There was only one solution I could see, get the laptop out and start typing the obervations in the free up space. I firstly switched the recording mode back to long-play and spent about 5 hrs typing up Thursday nights observations as above and deleting the files.

After this there was just time to wander up to the shed to catch Chris Toohey’s talk on the evolution of the eyepiece – all very interesting and one has to wonder how the early visual astronomers coped with the incredibly narrow fields their simple oculars produced.

After preparing the ‘scope etc for the night it was time for the big barbeque up at the top shed, the obligatory group photo and some more socialising before it was observing time again at 8.15pm under a darkening sky. I took an SQM at 8pm that was 21.28 and by 9.15pm it was 21.58 = +6.42 it was time for Hydra, Corvus and Crater.

The soundtrack for the evening was Meddle: Pink Floyd, Tales from Topographic Oceans: Yes, Incantations Mike Oldfield, Wish You Were Here: Pink Floyd and White Rock: Rick Wakemann.

This is no worse than mod faint, pretty diffuse looking object, found to the NNE of a mag 8 * by about 8' and seems weakly elong in that PA -- about 30? seems about 1.5 x 1' diameter, fairly consistent mod low SB growing azonally slightly to the centre without core or nucleus.

This wasn't too hard to see, in a pretty blank, thinly populated field. There is a curved line of 3 *s to the SW of the eg nr the field stop about 11' away. It has diffuse edges and lowish SB, no *s immediately associated, maybe weakly elong in PA 0 and maybe 1' x 50" rising slightly and broadly to centre azonally where there is a small weakly brighter round spot. About 10' NNW is another tiny faint nebulous spot adjacent to a mag 15 * -- NGC 3402 ???

See note from the NGC/IC project:

"Discovered by Common and placed at 10 50 09 -12 40 05 (2000). This places it 10 tsec of RA west but 1 degree north of N3411 at 10 50 26.1 -12 50 43.

This is a fairly small fairly faint eg which has a mag 13 and another mag 14 * on the E edge of the halo -- the brighter * is closest and just touching the halo. Seems round, 1.25' diameter or just over with fairly ill-defined edges growing broadly and slightly to centre. No evidence of zones or nucleus. Pretty blank field.

This is a really peculiar looking little eg, both on the DS and in the eyepiece. Mod to quite faint it is a small lens or fat bar shaped object of pretty consistent lowish SB mist that grows slightly to centre. It is elong about 1.25 x 30" in PA 120 but has no apparent core or nucleus. A tiny occasional outer halo seems to occasionally surround it to a slightly greater area. There is a mag 14 * just N of the E end of the halo and strangely a little tiny tail/trail of mist seems to curl off the E end firstly heading N and then W to terminate at that star. Intriguing!

The DSS pic shows a very unusual looking galaxy (s):

Starting with IC 767, though this is far from a bright eg, it is positively sparkling compared with the last few observed. Found to the S of the southernmost * of a pair that are about 2-3' apart in PA 0. Found near the southernmost. About 20" diameterr, round growing broadly and moderately to the centre azonally without nucleus. Its quite LSB but better than a few others tonight! 20' NW is IC 3024.

IC 3024 is a very faint and tiny eg that is very slightly elong in about PA 0, perhaps 20" across, very LSB growing weakly to the centre.

10' E of IC 767 is IC 768 which is a similar looking small patch of haze about 30" diameter just NW of an 11th magnitude star and has a broad weak central brightening to a very faint stellaring in the centre. 10' further E is IC769.

IC 769 is a comparatively bright and large eg, elongated in PA 30 it has a 50" x 30" LSB halo with a slightly brighter spot in the centre. Edges of the halo are diffuse and indefinite by 10' is IC3039.

IC 3039 is an almost stellar scrap of threshold brightness gossamer about 10" diameter with no discernable structure.

-41 is pointed at by from the S by a mag 7 and 10 stars about 3' apart. Pretty good SB, pretty bright oval in shape apparently an inclined spiral in PA 135, 1.5' x 1' rising broadly and slightly to the centre azonally and having a faint stellaring in the centre. From this eg -115 is found about 7-8' E.

It has much lower SB but not too bad. Round, growing from quite diffuse and indefinite edges broadly and weakly to centre without core or nucleus.


By now it was closing in on 2am and even though it was the changeover from EDST to EST giving an extra hr, I was well and truly buggered and did a bit of touring around some favourites before I bumped into M3 and decided to record it:

Still an impressive object -- a very large well resolved GC probably in the order of 12' diameter with a broad moderate concentration to centre . Est cc 6-7. Ragged edges and lots of resolved stars mag 12.5 down. The central core zone would seem to be about 3.5' diameter and not so well resolved due to the packed nature. Overall at least 200 *s resolved.

This is a pretty poor cluster all things told that sits astride a couple of mag 8 & 10 *s that are either side of it, the brighter is within the cluster, the fainter just outside to the S. A very diffuse looking hazy LSB object looking more like an eg except that most of the halo is slightly grainy and mottled with many very faint *s sewn in. Seems to have several faint sparkles across its face, maybe 5' diameter and round very diffuse edges growing broadly and slightly to centre with no apparent core zone.

This is a somewhat better object than IC 4499 (previous) but for such a large cluster it is not particularly well resolved. Seems about 7-8' diameter, very diffuse and hazy with obvious granular character -- particularly nr centre and it grows only broadly and weakly to the centre with no core zone or nucleus apparent. About 20 easily apparent resolved stars mainly in the outliers and several more threshold points that come and go with the seeing. There are several faint stars resolved nr the NW edge just outside the visible halo. Members??

By 3am I was out on my feet and had to climb into the cot for some rest. So after packing up I went to be with the temperature hovering over about 6 deg C.


Next morning we got up about 10am and unfortunately Gary Mitchell and Taylor had to return home. Many others returned home on the Sunday and by night-time the bus-park looked pretty forlorn it was just me on my Pat. Gary Mitchell’s 20” and Taylor’s 10” had gone as had Craig McIntyre’s C8 and Damien’s 8”. I had an ultra-quiet day after slipping into town for another kebab at lunchtime (yes they are very tasty) and out to Peter Van-Gent’s to pick up a bottle or two for a friend.

Most of the day was at least partly cloudy with low stuff from the northeast. I returned to Observatory Downs about 2pm and had a lay-down and in the end slept for two hours …

After an early dinner I went up for happy hour again and there was a heap of high cloud in the west, mixed with some low slow-moving stuff from the northeast – it didn’t look good at all at 5pm. While we all enjoyed a couple of drinks and nibbles, I quietly contemplated whether I should do a quick pack up and head for home. Common-sense won the day and I decided to stay – a good decision as it turned out.

After spending some time up in the big shed with Tony Austin, Col Shepherd and Arthur Hall, I took a peek outside at 8.30pm to discovered it was largely clear! So, it was back to the ‘scope.

As soon as I was completely ready to observe, the mid-low stuff started to toll in from the east again over Hydra, Leo and Virgo/Coma. So I pointed the telescope south where the sky was clear a pretended to ignore it. It worked as usual and 20mins later I was off to do some galaxies in Hydra, Corvus and Crater. Though it was a bit lonely, it only increased my productivity in recording observations. The SQM reading at 9pm was 21.51 = +6.38.

The soundtrack for the Sunday evening included Oxygene: Jean Michel Jarre, Abbey Road: The Beatles, The Mathematician’s Air Display: Pekka, Tubular Bells III: Mike Oldfield, The Firebird Suite: Igor Stravinski and Music of the Spheres: Mike Oldfield.

NGC 3865 is the larger and brighter of this pair and is a good sized oval shaped eg found about 6' SE of a tri of mag 9th & 11th *s.. Seems to be elong in about PA 1.75' x 1.25 growing broadly and slightly to centre there is an ill-defined weakly brighter core zone that brightens further to centre without apparent nucleus. Drawing a line from the Tri through -65 and continuing another 5' is NGC 3858.

-58 is a somewhat smaller, 50" diameter splash of haze with lower SB than -65, seems round growing broadly and slightly to centre with a very tiny weakly defined core zone but no real nucleus. There is a mag 12 * just off the W edge of the halo.

IC 2995 is a quite attractive, lowish SB eg that is very elong in PA 120, quite sizable about 2.75x 40" fairly consistent SB it is basically lens shaped but with blunt ends to the halo but well defined flanks, there is a mag 15 * which is just S of the SW flank, brightening broadly and weakly to the centre azonally and without nucleus. ESO 440-46 about 20' SW.

ESO 440-46 .is a very low SB much more diffuse eg with a mag 12 * N by about 1.5'. Appears as an amorphous blob of quite LSB that is round and grows weakly to centre azonally to the centre without nucleus. Seems about 1.5 - 1.75' diameter.

ESO 505-14 is to the NE of IC 2995 by about 20' and appears to be an elliptical by its brightness profile, 40-50" diameter, round and growing from indistinct edges, evenly and slightly to centre where there seems to be a faint spot type nucleus.

This eg is pointed at from the SW by a mag 9.5* and further SW a couple of mag 13 *s forming a tri tat points straight at it. Small very elong wisp of haze elong in PA 15, with a star embedded in the end of the halo at the SW very nr the tip, long streak shape, 1' x 10" growing broadly and slightly to the axis nr centre but no nucleus.

Now, to the NE by about 15' is the pair of egs, NGC 4105 and NGC 4106. These two have halos in contact and are quite bright. The brighter of the two is -105 and -106 is to its ESE. The nuclei are only about 1.5' apart, sharing a common halo that is in total about 3' x 1.5' in PA 135. Goth have good SB. The outer halo is of LSB. -05 is the brighter of the nuclei and it broadens broadly and slightly to centre where there is a somewhat brighter core and spot nucleus. -96, the core zone is a little smaller but contain a weaker stellaring. Almost due S by about 15' is IC 3005.

-005 is a very, very elongated sliver of weak mist with sharp tips in PA 160, about 3' x 10", grows broadly and slightly to the axis and slightly to centre. There is a mag 14.5 * adjacent to the W side of the N end of the halo. Really, quite a lovely object.

This is a slightly curious object that is diffuse and quite low SB. It appears as a somewhat flattened oval in about 1.5' x 1' in PA 90 it from slightly to centre but seems to have a weak bar running through it in the same PA. No *s immediately associated.

These three are basically in a line from NW to SE, -14, -22, -48 by 20 and then 10'. Starting with -22 in the centre, it is a small elong oval eg in about PA 15, about 1.25' x 30" LSB outer halo with indistinct edges growing slightly to centre where there is a small, round core zone about 10" diam which in turn brightens to centre but no real nucleus.

-14 is to the W of -22 and nr a short line of 4-5 very faint 8s. Small round eg about 50" diameter. No *s immediately associated rising broadly and slightly to centre where there seems to be a very small slightly brighter stellaring that is only weakly brighter than the halo.

-48 is about 3' N of a mag 12 * as a tiny, almost stellar spot of LSB haze, no more than 15" diameter.

This is a very diffuse quite LSB but sizable eg approaching 2' diameter, round has a very very faint * (mag 16) embedded on the edge of the halo to the SE of the nucleus. Grows broadly and weakly and broadly to centre without any zones or nucleus. The ESO eg pair lies 25' SW.

Both of these are very small or tiny and very faint LSB egs. The N most is -61 which is a small 15" dia spot of gossamer rising slightly to centre.

-59 is a very elong little streak of gossamer about 30" x 5" in PA 90 of consistent SB. Both are very faint.

Of this group, IC 4249 is the brightest and it appears to almost grow out of the side of a mag 11 * in PA 315. A small spindle about 20" x 5" of very low SB. NE by 6' is -53

-53 is a very distant eg, note the RV. Elong in PA 45, a very LSB small oval about 40" x 10" growing broadly and slightly to centre without nucleus.

ESO 509-38 is smaller and fainter and of lower SB about. Weakly elong in PA 45 lens shaped 20" x 5" rising hardly at all to centre with what appears to be a mag 16 * nr centre of maybe just to the NW of centre.

On the DSS this is a strange looking lumpy thing to the east by 3-4' from a mag 9 *. There are also two mag 13 * to the E and SSE of the eg just outside the edge of the halo. Pretty smooth looking halo with ill-defined edges 1.75' diameter growing broadly and weakly to the centre azonally and without nucleus. Possesses reasonable though lowish SB.

And that was the end for that part of the sky. With Leo now riding high on the meridian and the sky still 80% clear (most cloud was in the south) it was time to see some in The Lion. The SQM reading at 11pm was 21.69 = ZLM +6.48.

This eg is to the NW of a mag 8 * by about 13' and is pretty conspicuous object with a pretty "hard" looking, well-defined halo in PA 30, 1.5' x 10" , grows to the axis moderately, even in the outer halo and moderately to centre. At centre is a conspicuous bright spot type core/nucleus that is not quite stellar and about mag 13.5. Very pretty.

This is a lovely and very compact little Hickson group where it seems all 7 are visible, though 3 only very, very fantly. -51, -53 and MGC +4-37-30 are all small faint egs that form a RA Tri with the MCG eg at the RA and -53 southern most. The two NGC galaxies are about 30" diameter, round and about 30-40" diameter. -53 maybe weakly elong in PA 90 rising slightly to centre without zones. The MCG eg is a fraction smaller and fainter, maybe 20" diameter.

PGC 34899 is an almost stellar spot of haze appended to the southern edge of -51 while PGC 34901 is just E by 30-odd ". Both are no more than 10" diameter and very faint spots of gossamer.

IC 2759 is about 4' due W of this central group and is a little fainter that -53 and -51, about 30" x 20" in PA 0 brightening slightly to centre and contains a faint weakly brighter spot at centre. MCG +4-27-27 is just N of IC 2759 as a 15" diameter patch of very faint mist with no central brightening. All up the whole group is no more than 6' diameter.

P.A.: 72 Inclination: 6 R.V.: +2595 Source: RC3

This eg appears to the SW of a mag 10 * by about 5' and almost points at that star in PA45 as a reasonable SB but very small lens shaped halo about 40" x 10" growing broadly and mod to the centre azonally to the centre without apparent core or nucleus.

This eg appears almost due N of a mag 12 + 14 pair had has a mag 13 superimposition * just NE of centre of its small oval-shaped halo, about 1' x 30" growing slightly to centre without nucleus. Difficult to assess with that distracting star any structure.

This eg is pointed at by a mag 11 & 11.5 * which are away to the SE by a few arc-mins. Pretty small and faint eg about 30" diameter growing broadly and slightly to centre where there is a small weakly brighter spot.

Class: SBab P.A.: 11 Inclination: 5 R.V.: +6310 Source: RC3 *

These four egs are in a weakly curved line convex to the S about 15' long.
At the far W end is -53 whcih is barely S of a mag 10 * whcih is very distracting to the observation. Small, round halo maybe weakly elong in PA 0 about 30" diameter rising slightly to centre with a small weakly brighter 10" core zone.

-98 is at the E end and is pointed at from the SE by a couple of mag 11 *s. It is a very small oval halo of pretty LSB about 30" x 20" growing broadly and slightly to centre without nucleus. Between these to are from E to W -96 and -2857.

-696 is a very small, faint round spot about 30" diameter of LSB rising slightly to centre. -2857 is next about 3' further W as an extremely faint streak of gossamer 30" x 5" in PA 0 with no apparent central brightening.

This is a very very small very LSB round eg making a RA Tri mag 10.5 *s to its E. Seems no more than 30" diameter, round growing broadly and weakly to centre azonally without core or nucleus.

These two egs appear side by side 5' N of a mag 10 * and are only about 2.5' apart. -19 is the brighter of the two and slightly the larger and more diffuse, has a slightly less bright core and is weakly elong in PA 0, about 1.25' x 40" growing broadly and slightly to the centre where there is a small weakly brighter core zone. -20 is only about 40" diameter growing to s small slightly brighter core zone but no real nucleus.


And finally as he clouds became more and more troublesome, a few in Coma and then one in Canes:

P.A.: 150 Inclination: 3 R.V.: +244 Source: RC3

This eg appears pretty much to the E of a mag 9 * by about 7'. It is fairly bright, maybe slightly elong in about PA 45 growing broadly and mod to centre and at centre is a very small mod brighter spot-type core/nucleus that is somewhat brighter than its surrounding halo.

P.A.: 68 Inclination: 6 R.V.: -181 Source: RC3 *

This eg appears in a pretty blank field between two mag 13 *s that are sep by about 6' aligned NE to SW. A pretty small faint and diffuse eg that seems round or elong slightly in PA 45, 50" x 30" growing weakly to centre azonally without core or nucleus.

P.A.: 78 Inclination: 2 R.V.: +1995 Source: RC3

Tis eg appears in a thinly populated field with a few scattered mag 14 *s with about 4 quite nearby to the eg. Appears to be about 2 to 2.25' diameter, round of lowish SB growing weakly to the centre and no real nucleus.

This is a very small and dim eg which is pointed at from the NW by M98 about 10' away. Is not too far from a 13th mag *. Very small, round, 20-30" dia patch of consistent SB haze and brightens weakly to centre with no evidence of core or nucleus.

Class: SB(s)m: P.A.: 22 Inclination: ---R.V.: +809 Source: RC3

This is a very faint eg which is only at about 25 degrees elevation. It appears to stretched between two mag 12 *s aligned NNE-SSW about 2.5' apart. Appears as an ill-defined streak, 2.5' x 10" of consistent SB growing to the axis weakly and without apparent nucleus.

And now it was now over 60% cloud coming from the east and I decided that I was too tired to wait on with the long drive to Sydney before me tomorrow that enough was enough and did the full pack-up and put it all in the vehicle at 2am and shortly after hit the sack. The cloud at that point seemed to be thinning out a bit and when I got up for a comfort stop at 3am, it was totally clear again.

With the extra sleep I was up and 9.30am and by 11.30 I was on the way home after a superb weekend of observing. I can remember several Mudgee star-parties with more lively social-life, but I’m struggling to remember more that was more productive in terms of pure observing: More than 172 recorded observations and over 135 new objects bagged – and I was forced to miss a night without the recorder.

The drive home was largely uneventful save for a very dark rain/thunderstorm around Blaxland. Great stuff all round!

Thanks to John and Patti for hosting us again and thanks to all for making it a great weekend for the SASI.

Best,

Phew, Les!!!!!!!

I can honestly say that I did make an attempt to read all that, but just didn't quite make it, LOL! However, I did get the sense that:

A. You had a great time;
B. You saw lots of stuff!

Thanks for posting - even though I skimmed (and skipped), this sort of information will prove very useful on-line, because a search will pick it up! Great work!! Going to rest now - I think you should too...

Cheers -

Ditto to that, what a mammoth report! Did you really take that many notes!?

Wow, i'm exhausted just reading (skimming) it!

Top stuff Les, sounds like a great weekend. I was disappointed I could only experience the Ilford skies for 2 nights.

stuff me, that's a report and a half!

Excellent write up once again, makes for some good reading (and wishful thinking) during these extremely cloudy times.

Keep up the good work!

sure, but is your tunnelling electron microscope powerful enough to resolve the font size?

Thanks!

Hi All,

Thanks for the comments and I don't blame you for skimming (if you did).

I've been away for a week down the south coast catching up on some sleep and doing some full-moon binocular observing -- so I wasn't able to reply earlier.

For those who want to look for the highlights: There are some interesting Arp galaxies in there -- NGC 3509, IC 701, NGC 4861, and NGC 3836 -- which isn't in the Arp list but should be -- see the DSS pic. This quite peculiar looking eg would be a very interesting target for the Hubble Space Telescope I think.

I broke my ("normal" galaxy -- ie not QSO) distance record with PGC 32713 in Crater which has an R.V of +25133km/sec and assuming a Hubble Constant of 71km/sec/mpc equates to a distance of 1,153mly and it just happened by chance when I was looking at an adjacent eg -- NGC 3347.

And the other highlights included the NGC 4216 group of edge on spirals on the Virgo/Coma border, M100 and its retinue of dwarfs (I also saw indications of spiral structure in M100 for the first time), M98 and M99 and M a top-quality GC the north can be proud of.

Then there was the Boattini scare ...

The seeing was no better than okay during the four nights but the sky darkness was very good as evidenced by the SQM reading on the Friday of 21.84 and consistent 21.6-7s at most other times after 9.30pm. I never got a good look at Jupiter at all but Saturn was pretty good on the Friday around midnight holding x185 flawlessly and x247 occasionally.

Do I really take all those notes? Yep. If I hadn't have run out of recording space for night two when no notes were taken, I'd probably have recorded 250 objects for the weekend instead of 170-odd -- but it didn't do any harm to look at favourites either and to give some others a look at some showpieces like the Tarantula (NGC 2070, the Eta Carinae complex, M104, Centaurus A*, M83 etc, etc)

Besides forming part of the log once they are typed up, if you have a "system", it forces you too look hard and critically for detail that would be otherwise missed with a more casual glance. That is the other major reason for making notes. Drawing has a similar but probably even greater positive effect in this way. And the notes occasionally come in handy down the track ...

I hope to get back up to Mudgee again in either September or October -- I've got quite a bit of unfinished business in Pegasus, Andromeda and Cetus

Thanks again.

Best,

Les D
