This is a small quite elong eg in about PA 30 seeming to have a 16th mag * on axis at the NE tip. Just over 1' long x 15" very diffuse LSB outer halo. Good sized slightly brighter oval core and an occasionally visible stellaring in the centre.

-90 is found in a very thinly populated field and is a pretty plain-jane little thing. 1' x 45" in PA 150. Fairly LSB growing broadly and slightly to the centre without zones, core but seems to have a threshold mag stellaring or spot in the centre.
MCG +0-33-10 is 12' NW and is a very faint 20" diameter round spot of fog with a weak central brightening.

This is a really lovely very elong faint spiral in about PA 150 with an embedded star nr the tip of the halo at the SE end. Probaly 2.75' x 15" with a very diffuse LSB outer halo, large elong core slightly brighter than the halo but no real nucleus. The * at the SE end makes it look a little asymmetric and shorter at that end at first glance.
-18 is about 15' SE of -05 as a small oval glow in PA 150, about 40" x 20" with a diffuse edges growing broadly and slightly to centre and a very faint spot nr centre barely brighter than the halo.

this is a good-size oval mod bright eg which is probably the best part of 1.5' x 1' in about PA 45. Good SB halo growing broadly and slightly to centre without apparent zones core or nucleus. No *s immediately associated.. To the SE is a mag 13* 2.5' away.

This is a fairly small, round and ordinary-looking eg that is NW of an 11th mag * by 5'. Round, just over 1' diameter and grows broadly and slightly to centre without apparent zones or core. There are no *s associated.

This is a reasonable SB mod bright eg found 10' to the NW of a 10th mag *. Looks like a typical SA or SO eg, good SB halo just over 1' diameter growing broadly and slightly to the centre where there is a somewhat brighter small round spot in the centre.

This eg is between two 10th mag *s aligned NE - SW about 10' apart. Round probably 1.5' diameter, good SB grows broadly and slightly to centre where there is a substantially sized 20" diameter mod brighter core zone but no real nucleus inside.

These two eg's lie about 4' apart E-W of each other in a reasonably well populated field. Both are quite small and faint, 30" diameter. -19 is a little fainter than -20, and they both grow broadly and slightly to centre with no apparent core or nucleus.

This eg is found in a quite under-populated field to the SW of a mag 10 * by 5'. Very diffuse looking eg, 1.25-1.5' diameter with very diffuse edges. Round growing broadly and slightly to centre where there is a small weakly brighter zone but no apparent core or nucleus

Both of these are very small and faint galaxies. -21 is about 3' NE of -75. -75 is a small lens-shaped LSB object about 50" x 15" in PA 0 growing slightly in brightness to the centre but no apparent core or nucleus.
-21 is 3' NE and is a little fainter and lower in SB, round, about 30" diameter brightening weakly to centre with no apparent core or nucleus.

These two very tiny and faint egs are about 7' apart, N-S of each other with the NGC eg to the N. -91 is 30" diameter rising mod slightly and evenly to centre where there is a faint *ar nucleus. -30 is similar with a weaker brightening and no stellar nucleus.

This eg is not quite pointed at from the NW by a couple of mag 11.5 *s. Its pretty small, 40" diameter, round and grows slightly and evenly to the centre and nr centre moderately but no real zone, core or nucleus visible.

These four are arranged in a line running N-S in this order: MCG +3-41-12, NGC 6023, NGC 6022, MCG +3-41-8. The whole line is only 10' long. The two brightest is -23, followed by -08, -12 and -22. -23 is moderately faint about 40" across and grows broadly and slightly to the centre with no zones but an occasional hint of a stellaring in the centre. The others are similar but smaller and fainter with -22 perhaps the smallest and -12 the faintest. None of the other 3 have any evidence of nuclei.
