P.A.: 118 Inclination: --- R.V.: +16780 Source: RC3 *
This is a very small and faint eg, nothing more than a 15-20" diameter round spot of mist growing broadly and slightly to the centre azonally without nucleus. Note R.V!!

IC 1978 Galaxy *
RA: 03h 37m 05.4s Dec: -50° 09' 02"

Class: Sab? sp P.A.: 7 Inclination: --- R.V.: +10534 Source: RC3 *
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.

P.A.: 132 Inclination: --- R.V.: +11142 Source: RC3 *
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.

P.A.: 72 Inclination: --- R.V.: +1584 Source: RC3 *
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.

NGC 1476 Galaxy *
RA: 03h 52m 08.5s Dec: -44° 31' 58"
Mag: 13.9 (P) S.B.: --- B-V: --- Size: 1.3'x0.5' Class: Sa? pec
P.A.: 86 Inclination: --- R.V.: --- Source: RC3 *
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.

This eg is found about 13' away from a mag 6" which is to its NW by 12'. pretty good SB, round consistent, lowish to reasonable SB halo. 1.25' diameter with a weak central brightening and no core/nucleus.

-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.

Mag: 15.1 (P) S.B.: --- B-V: --- Size: 1.3'x0.2' Class: Sb? sp
P.A.: 28 Inclination: --- R.V.: --- Source: RC3 *
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'.
ESO 250-18 is a very tiny and faint streak/spindle of even surface brightness about 30" x 2" in PA 30 near a 7th mag * that is very distracting

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 ??
