IC 2106 is not too difficult to see, quite LSB which is a reasonable size slightly elong in PA 0, probably 1.5' x 1.25' with a broad weak central brightening. To the SW only a couple of arc mins away is a mag 14.5 *. E by 10' past a faint pair is ESO 422-13.

ESO 422-13 is a tiny extremely faint spindle of gossamer only occasionally visible with AV in PA 60, at best 15" x 5" .

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.

Best,
