Observing Report 28th & 29th December 2008 NGCLes -- Pt 1/3

Hi All,

Well after last month's three nights at Mudgee where no recorded observations were made because 2.2/3 were cloud or rain and the only night that was any good I just spent looking at favs.

The last month in Sydney has been largely cloudy at night so it was really plesant to get a completely clear night at my southern highlands site overnight on 28th-29th December.

After a day that threatened to spoil the party with some high and low cloud, by the time nightfall came conditions were excellent -- cloudless with quite good seeing -- i'd rate it 7/10 later on softening to 6/10. The SQM/L readings at 10pm was 21.33 and at 12.30am 21.39 equating to a ZLM of about 6.3. Ithought the reading a little suprising as the sky looked a tad brighter than normal and a fraction milky.

After touring a bit inc NGC 1791, NGC 1808, NGC 1535 (really, really lovely) and some other bright objects, I went on to some galaxies in Horologium high in the SW (darkest part of the sky). None of them were showieces by any means: but quite a lot of them had high R/Vs frequently indicating distances etween 500 - 800 million LY distance. That's Cambrian and pre-Cambrian times folks!

These three are in adjacent fields near the Horologium Hydrus border, within thinly populated star-fields. NGC 888 is a very small but fairly easily seen eg found not far SW from a couple of mags 12.5 -13.5 pairs each sep by about 1.5'. Seems to have a mag 14.5 * on the edge of the halo to the NW. Very small round eg, 20-30" diameter rising broadly and mod to centre but no apparent nucleus. Very small but reasonable SB. 10' N is ESO 115-3

ESO 115-3 is a very, very tiny spot of haze near the furthest of the two pairs of *s. Very, very faint and of very very LSB, max 10-15" -- no structure.

ESO 114-33 is one field due W of NGC 888 and is pretty similar, though a little fainter than 888 -- about 20" diameter and round.

This eg is in a pretty blank field except for a small distinctive RA tri about 15' SW made up of a mag 10 and a couple of mag 12-13 *s. Immediately visible, maybe slightly elong in about PA 60, fairly small, 40" x 20" growing broadly and slightly to the centre azonally without nucleus. There are several very faint *s scattered to its E, the faintest just off the halo.

Mag: 16.2 S.B.: --- B-V: --- Size: 0.7'x0.3' Class: Sd? pec
P.A.: 60 Inclination: --- R.V.: +13365 Source: PGC *

1136 is a mod faint, fairly small eg about 7-8' NW of a mag 8 *. Fairly small, round, 40-50" diameter with a lowish SB halo growing slightly to centre and at centre is a very tiny not quite stellar spot a bit brighter than the halo. Mag 15 *s to the N and E not far outside the visible halo. -35 is to the N by 3'. Overall SB is reasonable to lowish.

-35 is nothing more than a tiny scrap, 10-odd " dia and round, very very faint. Can only hold occasionally with A.V.

These two are both extremely faint and tiny edge on galaxies that are only occasionally detectable -- IC 1877 seems the fianter and I don't know who discovered it but they must have had good eyes and a huge 'scope assuming it was visual. Both are 10-15" long streaks or lines of mist indefinietly brighter than the sky's surface brightness. Really really faint, both seem in about PA 0 and near a short crooked line of 4 13th to 15th mag *s. The iC eg is the fainter.

P.A.: 99 Inclination: --- R.V.: +1037 Source: RC3

This is a mod low to quite low SB good sized eg, found to the SW by a few arc-mins from a small RA tri of mags 11-12 *s. Seems to be oval, in PA 90, 1.75 x 1' growing azonally to the centre without any evience of core or nucleus. Reasonable but lowish SB.

-33 is a fairly obvious, no worse than mod faint eg with a distracting mag 12 * at the S end of the oval halo. Elong in PA 45, oval, 1.25' x 1' ?? In PA 45 with good SB growing broadly and slightly to centre azonally without nucleus. Three other IC eg's are in adjoining fields -- -38, -20, and -42 all of which look essentially identical -- about 20" diameter, round patches of gossamer of which -42 is the brightest and -20 the smallest and faintes, though all are small, faint and difficult.

These four eg's are found within a field of a bright 6th magnitude * that is distinctly orange. NGC 1356 is about 20' W. -NGC 1356 there are a couple of mag 12.5 *s that point almost at it, fairly small maybe slightly oval eg, no round, the two stars point at it from the south. About 40-50" diameter growing broadly and slightly to centre azonally. There is a very verey faint * about mag 15.5 continuously visible with AV on the E side of the halo nr edge and two other stars slightly brighter on the SE & E outside the halo. IC 1947 is almost between the two mag 12 *s that point at NGC 1356. It is a tiny spot of gossamer, occasionally visible at best about 10" diameter.

IC 1950 is 8' SE and is a very small and faint edge on spindle of faint mist about 1.5' x 5" (if that) in PA 165 of consistent LSB.

5' SE of the 6th mag * is IC 1959 -- a really beautiful LSB edge on splinter of gossamer about 2.5' x 10" in PA 165, growing broadly and slightly to centre without apparent nucleus. A long tipped spindle.

This took a bit of finding -- very faint, found almost due S of a mag 7 * by half a field. It is very tiny, very tiny spindle 20" x 5" in PA 0 with no detectable central brightening. Note RV.

This is a pretty small and inconspicuous eg that is pointed at by a couple of mags 11 & 12 *s about 1.5' apart. Pretty small, 40" diameter growing broadly and slightly to centre where there is a small somewhat brighter core zone or spot. Not too hard to see.

This eg is found in a small bunch of four mags 12.5 - 14 *s which is only a few arc-mins dia. Very small and faint, round 30-40" diameter with a weak central brightening and no evidence of core or nucleus.

Both on the DSS and in the eyepiece this is a peculiar looking little eg. It looks like a short, oblong bar about 40" x 10" with definite squared off ends. Has good, almost consistent SB over the whole halo with no stars associated.

-12 is much the major member of this pair. Is a large and bright oval eg in about PA 45 3.5' x 2.0' with a much brighter 20" diameter core zone and a small spot in the centre of that. The halo has lowish but reasonable SB and there seems to be a weak bar running through it in the same PA. There are two faint stars involved mags 14.5 and 15.5on the NNE edges of the halo.

NGC 1510 is 4' SW and is a much smaller round spot, about 30" diameter rising evenly and mod to the centre with a tiny slightly brighter spot in the centre. NGC 1510 is pointed at bt -12.

This is an oval, almost tipped spindle in about PA 45, 1.75' x 20" with a consistent lowish SB halo and a small round, maybe slightly oval core zone about 15" diameter slightly brighter than the halo that has an occasional sub-stellar spot in the centre. ESO 250-18 is to the SE by 6-7'.

These 5 small eg's won't quite fit in the 12mm T II field and are all quite similar in appearance. The brightest is -61.It is to the N of a small RA tri of = br mags 13.5 - 14 *s. The side facing the eg has 4 faint *s in a row about 2' long in PA 90. Fairly small pretty diffuse LSB spot about 40" diameter, round with a broad weak central brightening and no evidence of core or nucleus. The -57 + -54 pair are 20' W

These two are basically the same -- 20-30" diameter round spots of V/LSB mist with a slight central brightening -54 seems to be the brighter. 10' S of this pair is PGC 15951 which is a very, very faint and small eg 10-odd " diameter with no central brightening. Only occasionally visible with AV

MGC +0-13-10 is about 25' S of NGC 1661 as a small spot about 20" diameter of extremely LSB, near threshold with a virtually stellar spot in the centre.

-70 is a pretty small slightly elong but otherwise pretty non-descript eg. Slight elong in PA 45, 40" x 15" it forms a RA tri with a couple of mag 13* to its S and SW and there are three other fainter stars in that group. Small round weakly brighter core and a wiff of a spot in the centre but no real defined nucleus. Quite LSB -78 is 30' NE.

-78 appears immediately E of the S most * of a I tri of similarly bright mags 11 & 12 *s. Seems to be small, slightly oval in PA 45, it is only 40" from the star, 30" dia with a sub-stellar nucleus in the centre of a consistently bright, weak halo. MGC+0-13-18 is nr the E most star in that tri and is even smaller and fainter but similar to -78 without the nucleus weakly elong in PA 45 ??

This group contains 7 eg's of whcih NGC 1684 is by far the brightest, -82 is 5' to the W and the others are arraanged arond them. NGC 1684 is 4' N f a 6th mag * and is a small but good SB eg and a little elong in PA 90, seems to grow broadly and slightly to centre where there is a weakly brighter round core zone but no real nucleus. -82 is smaller and slightly fainter and round and has a similar brightening profile to the centre.

10' N of -84 is -85 which is a very small faint eg, seeming somewhat lower in SB than -84 & -82 and is to the NW of a very faint *. 15" dia spot of very LSB consistent SB mist. Almost between -85 and -82 is an almost stellar spot of gossamer -83 -- no structure visible, very tiny.

-10' NE of -84 is MCG -1-13-33 that looks similar but a bit fainter than -85, about 15" diameter patch of gossamer. 15' W of -84 is MCG -1-13-22 which is just N of an 8th mag * that is quite distracting. It is a tiny elong streak of haze growing out of the side of a mag 14* in about PA 120, 20" x 5" and of consistent, very low SB. 10' further W is MCG -1-13-17 that is of similar appearance but in PA 30 -- very tiny too.

This is a trio of very small and faint eg's about 6' NW of a 6th mag. The three are very. very tiny almost stellar spots of haze -- took a bit of time to track down. MGC +0-13-27 is a bit brighter than NGC 1690, but all three are about 10-15" diameter, round growing weakly to centre. Took concentration to see them -- very easily passed over.

This is a very tiny eg with quite a few faint stars in the field. The DSS shows a much larger though V/LSB halo -- a somewhat peculiar ring-form barred spiral only a very tiny 15" spot growing mod and evenly to centre with a sub-stellar nucleus is visible.

There are 4 eg's in the one field with NGC 1713 being the dominant one and NGC 1719 in an adjacent field NE. -13 is the brightest, but still a pretty small, non-descript galaxy. -09 is only 3' W. -13 is about 50" diameter, round growing evenly and slightly to centre and at centre is an occasional substellar nucleus. -19 is adjacent to a mag 13 * and is somewhat smaller and fainter, about 15" diameter with an even slight concentration to centre with a hint of a sub-stellar spot in the centre.

The two MCG eg's are found side-by-side about 5' SW and are pretty similar in appearance to
-09 save being a little fainter. -53 has a 14th mag * on its edge that is brighter than the eg.

NGC 1719 is in an adjacent field to the NE as a very tiny spot of haze about 15" of very. very LSB with a 16th mag star on the S edge.

P.A.: 159 Inclination: --- R.V.: --- Source: RC3 *

-29 makes a tri with a mag 11 & 13 *s whciha re to its N and E, a fair size, nearly 1' diameter diffuse patch that looks a bit more like a small nebula than an eg. Round, weak azonal central brightening but seems slightly grainy.

-40 is about 20' E of -29 and is a small oval patch of mist, about 30" x 20" in PA 30 with a slight azonal central brightening and a 13th mag * at the SW end.

-53 is similar to -40 but perhaps a fraction smaller and fainter but otherwise similar -- except in PA 0.

This eg is just a little off-round in PA 0 and seems to have a 13th mag * superimposed at the SE corner. It almost makes a RA tri with two mag 12 * 4 & 5' away to the S and SE. Fairly soft diffuse looing halo, growing broadly and slightly to centre but without nucleus. 1.25' x 50" in PA0.

These are so small and faint they would be essentially invisible unless you knew exactly where to look. The two egs and a mag 12.5 * form a very tiny, less than 1' a side triangle with the star at the N point of the tri. Both are similarly sized, 15" diameter spots of haze that grow to centre where there is a substellar spot in the centre of each. Each is almost identical to the other.

P.A.: 120 Inclination: --- R.V.: +4826 Source: RC3 *

This is a very tiny eg, about 30" diameter that has a considerably brighter sub-stellar core/nucleus about 15' S of a mag 8 *. Two mag 15 *s point at it very close-by to the SW, the closes is nearly on the halo.



x185 27' TF

NGC 2110 Galaxy *

Mag: 13.2 S.B.: --- B-V: --- Size: 1.7'x1.2' Class: SAB0-
P.A.: 166 Inclination: --- R.V.: +2284 Source: RC3 *

This eg is found about 14' to the NE of a mag 5 *. Quite reasonable SB though small, round, 30" diameter growing broadly and mod to the centre where there is a faint substellar spot in the centre seeming occasionally stellar.

Wonderfully detailed report again Les, great stuff!

But I think we're going to have to have a little talk about your galaxy obsession, LOL!

Yeah, well I'm not going to try and defend myself on that point -- I do love them. The really faint, distant, difficult edge-on's are the best of all.

Beleive me though, I do look at other things and some of them are even bright objects!

One of the many things I personally enjoy about the really distant objects is the concept of "time-travel" -- in effect. For instance with IC 1942 in Pt 1, it has a recessional velocity of +18,340. Using this and assuming a Hubble Constant (H subscript "o") of 70km/sec/Mpc we get +18340 / 70 = 262 Mpc and multiplying by 3.26 (light-years in a parsec) we get a distance of 854.1 million light-years.

This is well and truly pre-cambrian times when the Earth looked "a bit different" -- to say the least. The only land-plants back then was a bit of pond-scum and some lichen. The rest was rocks, dirt and water. To me it is fascinating and awe-inspiring that the light you are looking at from this tiny, faint galaxy left its source when the Earth looked so dramatically different and spent nearly (in context) a billion years tearing across the cold reaches of intergalactic space just to hit my telescope mirror and form an image. I think about what the ground around me must have been like 850 million years ago and what has happened since then.

Really, if that isn't awe-inspiring, I dunno what is. Makes me feel a bit special anyway.

Thanks for the comment!


Best,

Les D

Hey Les I have been all morning reading your articles on this object or that... where to look, what to expect etc, and I have to hand it to you neat stuff there and here...

I personally thank you for the many objects you have guided me to over the years... yours has been the only guide I have ever used now that I think about it... nice day for all the old mags.

You do a great job and I salute youalex

Many Thanks

Hi Alex & All,

Well, what can I say except to say thank you and blush a little.

That is the major reason I write -- in the hope I can lead others to the point where the sky and the Universe itself will inspire them to bigger and better things in their own astronomy.

When I post my "bulk observations" in this thread I sometimes worry that some people might see it as a self "ego-massage" -- in some way. There is a much better vernacular expression for "self ego-massage" but I won't use it here -- I think you get the picture without further clarification.

But that's not the reason at all.

The major reason I post them here is to demonstate that I live what I write -- I am an observologist: here is the proof. When I write stuff on observing, the appearance of things in the eyepiece comes from my notes of my observations through my telescope(s).

Other observing writers I have admired over the years like Walter Scott Houston, Leyland Copeland, Peter Williams, Sue French, Steve Gottlieb, Alan Whitman, Dave Eicher, Jenni Kay etc etc (not an exhaustive list) have the same Modus Operandi.

When you read their stuff it is clear they are real observers who observe with real telescopes and that they love what they do. Take the writing away and what would they be doing? Observing! Nothing would change. Personally, I love reading that sort of stuff from those sorts of people and it pushes me to see more and more -- as much as I can, while I still can.

In the same way I also love it when others post theirs here -- I like to read what they're doing, what they're seeing and how it looked -- no matter how you do it or with what telescope.

Thanks for the compliment Alex -- much appreciated.


Best,

Les D

Spot on Les, I always dwell on these things when I am observing, thinking of the incredible journey of those photons through time and space, the thin, ever-expanding bubble of light from ancient events that still has enough power to register on your retina as it sweeps past Earth. Of course my window to the past is somewhat shorter than yours, but with the help of a basic CMOS sensor I can capture traces of ancient light from objects like qasars that belong to the infant universe, before our Sun and solar system existed, but that shine like beacons through the aeons. And some of the brighter extragalactic supernovae, ancient cataclysms that appear like dim Milky Way stars - just imagine the vast regions of those galaxies that must have been sterilised by these events. Of course, we never know what light of 'new' events is about to sweep over us from night to night as we observe - let's hope that if it's a cataclysm, it's travelled a long, long way!!!

Cheers -

Personally I dont know how you do it..I used to keep heaps of notes but I just get carried away and cruise around most times ..add to that often I dont know the name of the object and to find out will destroy my vission I just take in the beauty...

I read all your old articles today... I keep the mags open at your page and pull out last years or the years before to see what may be worth looking at for the coming month ....

I never have seen your work as an ego trip and if it is there is no need to worry..being ego driven is ok keeps you going if nothing else..but I like your higher good intentions..senced same and that prompted me to mention how for at least one person your input is invaluable.
