x185 27' TF

IC 3024 Galaxy *
RA: 12h 10m 11.9s Dec: +12 19' 31"
Mag: 15.1 (P) S.B.: --- B-V: --- Size: 1.0'x0.3'
Class: S? P.A.: 169 Inclination: 6 R.V.: +8753 Source: RC3 *

This is again an extremely faint and tiny elong eg, patch of gossamer at best 15" x 5" in PA 0 with no central brightening apparent. Very faint.

IC 3025 Galaxy *
RA: 12h 10m 23.0s Dec: +10 11' 20"
Mag: 15.4 (P) S.B.: --- B-V: --- Size: 0.7'x0.3' Class: S0?
P.A.: --- Inclination: --- R.V.: +506 Source: RC3 *

Through the eg this is a very very small slightly elong eg between but a bit more towards the N most of a couple of mag 13.5 * aligned roughly N-S. separated by 2'. Probably 20 x 10" in PA 0 brightening broadly and weakly to centre without zones or apparent nucleus.

Starting with IC 767, though this is far from a bright eg, it is positively sparkling compared with the last few observed. Found to the S of the southernmost * of a pair that are about 2-3' apart in PA 0. Found near the southernmost. About 20" diameterr, round growing broadly and moderately to the centre azonally without nucleus. Its quite LSB but better than a few others tonight! 20' NW is IC 3024.

IC 3024 is a very faint and tiny eg that is very slightly elong in about PA 0, perhaps 20" across, very LSB growing weakly to the centre.

10' E of IC 767 is IC 768 which is a similar looking small patch of haze about 30" diameter just NW of an 11th magnitude star and has a broad weak central brightening to a very faint stellaring in the centre. 10' further E is IC769.

IC 769 is a comparatively bright and large eg, elongated in PA 30 it has a 50" x 30" LSB halo with a slightly brighter spot in the centre. Edges of the halo are diffuse and indefinite by 10' is IC3039.

IC 3039 is an almost stellar scrap of threshold brightness gossamer about 10" diameter with no discernable structure.

IC 3046 Multi-Galaxy Sys *
RA: 12h 13m 07.8s Dec: +12 55' 05"
Mag: 15.3 (P) S.B.: --- B-V: --- Size: 1.5'x0.3'
Class: S? P.A.: 134 Inclination: 6 R.V.: +8096 Source: RC3 *

This is a very very faint and small eg making an eq Tri with a couple of mag 11 & 12 *s 4-5' a side. A small streak of gossamer in about PA 135 with threshold surface brightness with no central brightening and perhaps a slight hint of a stellaring in the centre.

IC 3078 Galaxy *

IC 3081 Galaxy *
RA: 12h 16m 09.1s Dec: +12 41' 29"
Mag: 15.4 S.B.: --- B-V: --- Size: 1.0'x0.4'
Class: E P.A.: 86 Inclination: --- R.V.: --- Source: PGC *

This is an extremely faint and tiny eg which is not quite pointed at by a couple of mag 14 *s to its North. A very small round ephemeral patch of haze 15" rising broadly and slightly to the centre without nucleus.

17' NE is another pair of very similar objects -- IC 3078 and 3081. These two are E-W of each other separated by about 3'. They are virtually stellar patched of mist that are only occasionally visible as the seeing allows. No more than 10" diameter.

NGC 4200 Galaxy *
RA: 12h 14m 44.2s Dec: +12 10' 50"
Mag: 13.9 (B) S.B.: --- B-V: +0.90 Size: 1.7'x1.0'

IC 3063 Galaxy *
RA: 12h 15m 06.8s Dec: +12 00' 59"
Mag: 14.8 (P) S.B.: --- B-V: --- Size: 1.1'x0.5'
Class: Sa P.A.: 20 Inclination: 5 R.V.: +2378 Source: RC3 *

NGC 4200 is a small, faint and slightly elong eg in PA 90, about 30 x 20" with a broad slight azonal increase in brightness to the centre but no nucleus or core. IC 3063 is 10' SE.

A very small tiny and faint eg found nr the br * in a rectangle made up of 1 mag 13 and 3 mag 14 *s. 15" diameter patch of mist rising to a very faint substellar nucleus.

IC 3105 Galaxy *

Mag: 14.7 (B) S.B.: --- B-V: --- Size: 1.8'x0.5'
Class: Im: P.A.: 27 Inclination: --- R.V.: -158 Source: RC3 *

These three egs are found in one field making a 9' a side Eq tri with IC 3099 at the northern vertex. -100 is due S and -05 to the SE.

099 is a very tiny streak of almost a line of gossamer 30" ling x a few arc-seconds wide in PA 0 and a substellar spot in the centre. It points at a mag 13* to the S by a arc mins.

-105 is very similar to -099 except in PA 30. Only occasionally visible, 30" x 5" with no apparent core/nucleus.

-100 is also very similar in PA 30 but possibly slightly fainter that the other two. Otherwise looks the same.

The brightest of these four by some distance is NGC 4035 which is a quite bright very elong eg in PA 45, about 2.5' x 20" . Good SB halo growing broadly and slightly to centre where there is an elong weakly brighter core zone. NGC 4224 is to the NW by about 20'.

-224 is a somewhat smaller and fainter oval eg about 1.25' x 40" in PA 45 with a broad slight concentration to centre without zones or apparent nucleus.

NGC 4246 is E of -35 by 9' as a as a slightly elong small oval about 1.25' x 45" in PA 90 with a weak central brightening. Not too hard to see it is diffuse and LSB no zones.

NGC 4247 is due N by 5' from -46 with similar surface brightness, round 30-40" diameter rising broadly and slightly to centre without apparent nucleus. Very LSB.

Pt 8 to follow ...
