NGC 2960 Galaxy *
RA: 09h 40m 36.4s Dec: +03° 34' 37"
Mag: 13.3 (P) S.B.: --- B-V: ---
Size: 1.7'x1.1' Class: Sa? P.A.: 40 Inclination: ---
R.V.: +4722 Source: RC3 *
This is a fairy faint eg that isn't too hard to see in a field with only a few faint stars. It is pretty much to the W by 4' from a mag 11 *, fairly low seemingly consistent SB with very diffuse edges, 50" to 1' diameter, round but contains at centre a very tiny, few arc-seconds faint stellaring/spot type core/nucleus that dominates the halo which has low consistent SB.

IC 2541 Galaxy *
RA: 10h 05m 47.9s Dec: -17° 26' 06"
Mag: 14.4 S.B.: --- B-V: ---
Size: 1.2'x0.5' Class: SB(r)bc? P.A.: 5
Inclination: --- R.V.: --- Source: RC3 *
This is a quite small fairly elong eg in PA 0, found to the S of and near a small zig-zag line of mag 13 & 14 *s . Appears as a small LSB lens-shaped object in PA 0 1' x 15" with an azonal slight brightening to the centre with no apparent core or nucleus. Not too hard to see. SB is lowish but reasonable.

Of these two -40 is the dominant member but is still small and faint -- -41 is an extremely tiny eg that is also very faint. -40 is small and faint, round, about 40" diameter, quite to very LSB with no real discernible brightening -- certainly no zones or core/nucleus and no other structure visible. -41 is about 1 or 2' SW and is slightly fainter and even lower in SB, maybe 10" diameter and slightly elong in PA 0. Very, very low SB.

-45 is the major of this pair and is a fairly bright eg found only 8' SW of a 4th mag * Lambda Hydri. that must be excluded from the field to be seen well. It is a bright eg elong in PA 0, 2.25' x 1' with a LSB outer halo with a small round 20" dia mod brighter core zone that also brightens slightly to centre. Easy to see, a pleasant object. -43 is 8' to the S.
-43 is a very small LSB consistent SB spot of gossamer about 30" diameter, round and has no structure. Pretty faint.

NGC 3146 Galaxy *

Size: 1.0'x0.8' Class: SB(r)b? P.A.: 90
Inclination: --- R.V.: --- Source: RC3 *
This is a pretty easy to see eg which is due S of a mag 10 * by about 5'. Presents as a small round splodge, 40-50" diameter with a somsistent SB halo whcih is ill defined at the edge and a very small somewhat brighter core/nucleus that is overall pretty easy to see.

NGC 3178 Galaxy *
RA: 10h 16m 09.0s Dec: -15° 47' 28"

his eg is in a field which is reasonably well populated with stars considering it is a fair distance from the galactic equator. 8 * br than mag 11 with 1 9th. Small round eg just under 1' diameter with good SB -- pretty easily picked up and brightens without zones mod and slightly to centre without apparent core or nucleus. No *s immediately associated.

NGC 3290 Arp 53 Galaxy *

Note the R.V ! This eg is found due S of a mag 7 * by about 5' and is of fairly LSB but only mod faint. Small, just under 1' diameter, mod faint, mod LSB but seems to be evenly illuminated with a consistent SB across its face. No discernible core or nucleus.
By now it was nearly 2am and we decided to start packing at 2.30am and time for the final few favourites. We took a (another) look at Saturn, M83, Cen A*, Omega Centauri and a couple of others. At 2.15am, the secondary was dewing again and would have taken 10 mins to warm up, so I gave in and packed. Gary followed suit 10mins later and we drove off with Scorpius climbing and the winter sky well on the way.
When we got the Mobil I discovered that all my hard work in cleaning the car earlier in the day was wasted. My feet were caked with orange muddy sand. The driver’s compartment was the same and the Pajero was 10 times dirtier than it had been before I washed it, from 1 trip up and one trip down the old air-strip. Yes it was that wet!
After a quick de-brief at the Mobil I got home at 4.30am. Very tired, very contented after a totally unexpected evening of excellent observing.
The sky, as we all know can be a cruel mistress, but from time to time she can surprise you as it did last Saturday night.
Best,
