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.

NGC 1096 Galaxy *
RA: 02h 43m 49.1s Dec: -59° 54' 45"
Mag: 13.5 (B) S.B.: 13.8 B-V: +0.73 Size: 1.9'x1.8'
Class: SB(rs)bc P.A.: 32 Inclination: --- R.V.: +6682 Source: RC3 *

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.

This eg is found 12' S of a 9th mag * This is a small mod faint eg that wasn't immediately obvious. Small, diffuse spot 40-50" dia growing weakly to centre without apparent core or nucleus.

-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.

This is a fairly small, faint and non-descript eg with low to very LSB, round, 30" dia growing broadly and slightly to centre without apparent nucleus. There is a mag 15 * on the S edge of the halo.

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.

Pt 2 to follow ...
