Observations from 9 & 10 November 2007 Pt 1 -- NGCLes

Hi All,

Just thought I'd post some observations from an observing weekend near Mudgee last weekend. The observation of Holmes (first was on the night of the 9th) and the rest on Saturday the 10th whcih was an excellent night. Most of the objects are in Aries, Caelum and Columba and are pertty faint but I do like to hunt the obscure where often unearthed gems lay.

Most observations were with 12mm and 9mm Nagler at x 185 and x247

17/P Comet Holmes 15x70s & 25cm

This comet in outburst is an easy naked-eye object even at the low culmination altitude of about 7 degrees. Naked eye it appears to be similar in brightness though about a magnitude dimmer than Mirfak (Alpha Perseii). Halo size is somewhat larger than 47 Tuc and a little larger than M41. Est magnitude 2.6 – 2.8.

In 15x70s it is a bright circular object about 0.75 degrees in diameter. The edges of the halo/coma have very well defined edges and has very high surface-brightness -- comparable to most of M42, It brightens moderately and broadly to the centre though no apparent pseudo-nucleus is visible.

In G Mitchell's 25cm with 26mm T5 is a very bright and large object, a little under 0.75 degrees diameter. The N edges of the Halo has an exceptionally well-defined edge for about 225 degrees of the circular halo. The remaining 135 degrees pointing southward is somewhat less defined and it seems "blown-out" in a southward direction -- looking a bit like a jellyfish. It brightens broadly and moderately to centre and has high surface-brightness. There is a somewhat smaller, maybe 10' x 7' tear-drop shaped, weakly brighter zone in PA 0 deg almost centred within the halo but a little off-set to the S in the direction of the "blow-out" and a suspicion of a vaguely brighter spot in the centre just off-set to the South.

First item on the agenda was the other comet – 2007 F1 LONEOS which was about 1.5 degrees NW of Epsilon Scorpii. It took the best part of 7-10 minutes careful scanning to finally pin it down at exactly the predicted position making a right-angled triangle with a couple of slightly brighter mag 7.5 stars – but what a disappointment
It was tiny and faint and – a flop! The notes follow:



Comet 2007 F1 Loneos 15x70mm
A very disappointing object. Found just S of Epsilon Scorpii it is a tiny object less than 3' diameter, like a hazy mag 8-9 star with a tiny halo and no tail. Big, big disappointment!

Before I got into my list it was time for a wander through some old favourites and this is basically where I went. First to M33 which was particularly stunning this time last year at John’s and it was still the same. Stephan’s Quintet was pretty too.

I then went to a few low-surface brightness galaxies like the WLM and NGC 45, NGC 247 and NGC 300 and then had a bit of a spin through the Fornax cluster and a few of the nicer barred spirals of the spring sky like NGC 1365, 1097 and NGC 1300 –Yum! Then M77 and a number of its surrounding galaxies in Cetus and then I checked in on Mira which was a little fainter than I expected it to be. One other spring favourite of mine, the faint sliver of an edge-on spiral in Pisces -- NGC 100 was stunning.

Then it was time for a poke around the LMC and SMC. That done it was time to devour some galaxies in Aries and these are the observations;

Size: 0.7'x0.6' Class: S0? pec P.A.: 166
Inclination: --- R.V.: +2935

Starting with 678, it is a elong eg diffuse in character and has a very faint outer halo and a comparatively bright nucleus. Overall it seems 2.5' x 30" in PA 75 with a small 30 x 10" mod brighter nuclear area. The tips are of very, very LSB by comparison.

-80 is to the ESE by 5' and presents as a fairly small round eg about 1' diameter growing mod and evenly to centre and at centre suddenly to a very small sub-stellar nucleus.

-94 is to the E by 15' from -80 and is a very tiny, almost stellar scrap of haze about 10-15" diameter of very low S.B with no discernible brightening.

-91 is SSW by 15' -- a much larger eg than -94 appears next to a faint "snake-eyes" pair of mag 13.5 *s and they are to the SW by 1.5'. That pair almost points at the eg. 50" diameter, perhaps an early type spiral with a very faint outer halo dominated by a somewhat brighter very small core and sub-stellar spot occasionally visible

Size: 2.1'x1.6' Class: SAB(s)c P.A.: 0
Inclination: 2 R.V.: +5241

Fairly small, pretty LSB eg, probably only 1.25 - 1.5' diameter, maybe slightly oval in PA 0, and to the ENE by 2.5' is a mag 9.5*.It is a quite diffuse object growing broadly and slightly to the centre with no zones or nucleus. The SB isn't too bad but is pretty low.

NGC 697 Galaxy *
RA: 01h 51m 17.4s Dec: +22° 21' 27"

Size: 4.4'x1.4' Class: SAB(r)c: P.A.: 105
Inclination: 6 R.V.: +3117

This is a lovely elong galaxy about 1.75' x 30" in about PA 120 found to the W of a small group of faint *s. Appears to be an edge on spiral or inclined spiral, mod LSB grows in brightness slightly to the axis near centre and slightly and azonally to centre. At centre is a small weak streak-like core but no real nucleus.

Inclination: ---

NGC 776 is the dominant member of this pair. IC 181 is also nearby but not seen. NGC 776 is a fairly faint, quite diffuse small eg, maybe about 1' diameter quite to low SB. Brightens broadly and weakly to the centre without apparent nucleus and no stars directly involved. IC 180 is S by 3'.

IC 180 is just a tiny 5-10" diameter scrap of gossamer only visible intermittently with concentration and A.V

Mag: 13.9 S.B.: --- B-V: ---
Size: 1.2'x0.8' Class: E? P.A.: 18
Inclination: --- R.V.: --- Source: RC3 *

NGC 881 is a very elong eg, possibly edge on spiral which is found pretty much due E of a mag 11 * which is not far off the E flank. It is of LSB but reasonable, approaching 2' x 20" in PA 150 with a small similarly small, slightly elong slightly brighter core/nucleus. 10' SE is NGC 883

NGC 883 is a small round, faint eg of very LSB. Probably just over 30" diameter with a slight central brightening. And a very tiny mod brighter core/nucleus. An uneven mags 11 + 13 pair is just to the S. IC 219 is 10' SW.

IC 219 is just a tiny scrap of gossamer about 10" diameter with no stars involved.

About this time some odd cloud was starting to form here and there – not the serious type it only ever covered about 20% of the sky at most but sort of formed in little bunches, stayed put where it was and then dissipated 10 minutes later. Nuisance value more than anything but one spot it seemed to like to form was over Aries. I headed down the shack at about 11pm to make a coffee convinced that if I payed no attention to the sky for 15 minutes it would go away. Coffee over, I stepped outside to a cloudless sky and re-started on my list. The moment I pointed the ‘scope at Aries, there it was again on and off for the next hour. The moment I finished in Aries about 1am, it went away. After last night’s odd event with Holmes being in the clear for about 90 mins, normality it seems had been restored.

Size: 4.3'x2.0' Class: SA(s)c: sp P.A.: 7
Inclination: 6 R.V.: +2100 Source: RC3 *

This is a quite elong possibly edge on spiral found almost due E of a mag 10 * which is just off the flank of the halo. It is of LSB but not too bad, approaching 2' x 20" in PA 0. Long slightly tapered oval with a small slightly brighter core but no apparent nucleus.


x185 27' TF

NGC 820 Galaxy *
RA: 02h 08m 25.1s Dec: +14° 21' 00"
Mag: 13.6 (P) S.B.: --- B-V: ---
Size: 1.3'x0.7' Class: Sb P.A.: 61
Inclination: 4 R.V.: +4422 Source: RC3 *

This is a very small, pretty non-descript eg in PA 30 and is only slightly elong. It appears between a couple of mag 14 & 15 *s It would seem to be maybe 50" x 20" in that PA with a slight to moderate broad concentration to the centre without apparent core or nucleus. The closer of those two stars is the one to the N, maybe just over 1' away.

NGC 930 is the middle galaxy in a line of three inc -24 and -38. It is a fairly small round eg about 40" diameter. Mod faint and of lowish SB brightens evenly and slightly to centre. At times you suspect a very faint occasional stellaring in the centre. Between two stars of mags 11 and 13.

-24 is NW by 20'. This is a pretty small, faint, non-descript eg about 45" diameter, round and brightens broadly and slightly to the centre azonally to the centre with a very faint *ar nucleus.

-38 is ESE by 10' Small and pretty ordinary eg about 40-50" diameter with diffuse edges and rises evenly and moderately to the centre but no real apparent nucleus.

NGC 976 is a pretty small and non-descript eg which forms an I tri with 4 stars, 2 to the NNE and 2 to the NNW all mags 12 to 14 with the eg at the sharpest point and at the S. It appears to be round about 40" diameter lowish SB growing broadly and slightly to centre azonally without apparent nucleus. MCG +3-7-28 is to the SE by 20'.

MCG +3-7-28 is a very faint eg, perhaps slightly elong in PA 0, a weak patch of consistent SB haze without nucleus about 30" diameter.

This is a quite attractive elong or near edge on eg, a faint spindle shaped object in about PA 15, seems to be about 1.5-1.75' x 15" and a slight brightening to the axis near centre. A mag 14 sparkle is embedded near the centre, just off axis to the E near the core barely within the halo.

NGC 1134 is an easy to see eg in a pretty dim field. Mod low SB, appears to be elong in PA 150 1.25 - 1.5' x just under 1' with a weak streak through the major axis and a small round brightening at centre that takes concentration and AV to see. a mag 14 * is adjacent to the core off the halo to the E.

IC 267 is S of 1134 by 10'. A quite faint quite elong eg in a pretty blank field. a fat lens shape in PA 0 maybe 1.25' x 20" growing in brightness weakly to centre. Very low SB

These two galaxies are at the centre of AGC 3301. Both of these are very small and at least quite faint. NGC 1759 is easily the brighter and larger, round probably 20" diameter growing broadly and mod to the centre without apparent nucleus. There appears to be a mag 15-16 * due S just on the edge of the halo. Almost due N is the companion MCG -6-12-1.

MCG -6-12-1 is found about 1.5' N of NGC 1759 with a mag 13 just N of it. A very very tiny 10" round spot of very faint haze, much harder to pick up with a slight central brightening.

NGC 1812 and NGC 1811 are in a close pair with the ESO eg some distance away to the SE. NGC 1811 is a very thin small spindle in PA 60, about 40" x 10" brightening to the axis particularly near centre mod and evenly, but no real core but the suspicion of a faint sparkle near centre. It points at -12.

-12 is 2.5' to the NE of 11 with a mag 13 * between. More round and quite small, about 40" diameter with a slight broad central brightening. Maybe slightly elong in PA 0 with a faint spot in the centre. ESO 422-40 is to the SE by 15', looking somewhat like -11 by in PA 45 and a little fainter, 40" x 10" and lens shaped with a slight central brightening.

This pair are at the centre of AGCS 521. Fairly easy to pick up, the IC eg somewhat the brighter. IC 2122 is fairly small, round mod faint and seems to be about 45" diameter with an ill-defined outer halo brightening mod to a faint spot-type core nucleus. ESO 362-15 is 4' SE.

ESO 362-15 is a lower SB round smudge about 20" diameter with a very faint spot in the centre hardly brighter than the halo.

Another pair lie 1/2 a degree E -- ESO 362-11 and ESO 362-12.

The first of these -11 is a classical-looking very attractive and faint edge-on spiral that points at -12. Seems to be probably 3' x 10" thin lens shaped halo with very faint tips. in PA 75, brightening broadly and slightly to centre but doesn’t seem to have a defined core zone or nucleus. A mag 9 * is to the SSE by 3'. . -12 is to the NE by 5' is a pretty small scrap of haze about 20-30" diameter, round, with a slight central brightening.

This is really quite odd-shaped and peculiar looking eg on the DSS image but shows none of this visually. Probably round or slightly elong in PA 30, found not far from a mag 10 *. Fairly low SB 2.0' diameter brightening broadly and slightly to the centre azonally without apparent nucleus. Looks diffuse with ill-defined edges and no stars associated.

IC 2135 is a very beautiful edge on thin spindle eg -- seems like a late type spiral in about PA 120. Probably 3' x 10" of fairly consistent SB growing weakly to centre with no defined core or nucleus. A stars is at the NW end of mag 14 and at the SE end by just over ' is a star-like spot MCG -6-13-5. This eg is really tiny, 5-10" diameter almost stellar very faint spot.

These two eg s are part of AGCS 536. Both are pretty small fairly faint eg s -89 is pointed at by a couple of mags 10 *s just N.. Round, nearly 1' diameter growing broadly and slightly to the centre without nucleus. S by 7' is 1992 which has slightly lower SB, a bit more diffuse in character, 45" diameter growing broadly and weakly to the centre azonally without apparent nucleus.

This is a pretty starry field for Columba, but it is a pretty ordinary little eg., about 45" diameter, round, grows broadly and slightly to centre with a hint of a fairly large weakly brighter zone in the centre but no real nucleus.

And that cleans out Columba and Caelum down to 15th magnitude – you’d never guess there were 50 worthwhile galaxies in total there to see in this apparent desert.

Now near 3am it was time for the obligatory look at M42. Yep it was as stunning as usual and quite a bit of colour visible without filtration, in the main blues, and browny-russets here and there in the wings.

The to the Horsehead nebula with the H-Beta filter with the 20mm T II and as I noted last year, this is a really simple object in this aperture with this magical filter. Then some PNe in Canis Major and Puppis finally ending on a new one close to M46. Now I know what you’re thinking NGC 2438 that is superimposed on the northern outskirts of M46. No, it is SA 2-15, on 15 arc-mins further north of NGC 2438.

This PNe took quite a long time to finally pin down -- seems pretty faint for mag 14 to me! Found about 0.5 degrees N of the centre of M46. About 30" diameter, faint evenly illuminated disc in a rich field to the W of a fairly bright "Corvus-style" quadrangle asterism of *s about mags 8-9 and in the midst of a tri of mag 13 *s, a faint haze with no central brightening, translucent, greyish. Not really visible without filter.

Nasty but good fun. The only reason I thought to look for it was my up-coming column in Jan-Feb 2008 AS&T.

Great reports Les, I presume all the observations were with the 18" ?.
I will give some of them a go in the 16", by the looks of things not all of them would be visible or very very difficult.
Just one quibble I thought you were using Dryer discriptions such as LSB but after checking it means Low Surface Brightness.
The chances of getting some of those objects observed this year are dissapearing fast and with the Moon and the lousy weather, looks like it could next year before I observe them
Thanks
Ron

Good report and very nice galaxy descriptions Les!

Yes, Loneos is fading fast - I think we've all been spoilt by McNaught! I had the pleasure of viewing 17P/Holmes last week though for the first time, and would have greatly appreciated your 7 degrees! Low, only 2.75 degrees altitude (viewed from flat farming land just NW of Bendigo, Vic) and it was a really special sight all the same. Easy naked eye, brighter than Andromeda, and rather like a large globular cluster but with flared central brightening in 12 x 50 binoculars. Seemed larger in size than 47Tuc. Now know what everyone's raving about!

Cheers -
