This 4 are all members of AGC 1108. -99 & 05 are the dominant 2 though all are very faint.

-99 is imm E of a mag 14 * which is just outside the halo. Round, small spot 15-20" dia growing slightly to centre without zones or nucleus. -05 is E by 4'.

-05 and MCG +3-28-15 have touching or merged haloes E-W of each other. Each is about 15" diameter rising broadly and slightly to centre. Both are fainter than -99.

PGC 32419 is a couple of arc-mins N of the latter 2 and is no more than a tiny almost stellar spot of gossamer with no central brightening apparent.

RA: 10h 51m 17.6s Dec: +13° 56' 47"
Mag: 13.5 (P) S.B.: --- B-V: --- Size: 1.2'x1.0' Class: (R)SAB(r)0+

P.A.: 137 Inclination: 7 R.V.: +3048 Source: RC3 *

This is a very small eg that seems to be involved with a mag 14 * which seems to be just off its E flank. Small, round, 30" diameter seems to grow broadly and mod to centre where there is a very faint *ar nucleus which for an object this faint and small seems out of place.

-19A is 4' N and is a very tiny slash of extremely LSB haze in PA 135 that is about 30" long and a hair's breadth wide and no apparent nucleus. It makes a RA tri with mag 12 & 13 *s to its SE and SW.

-25 is found just to the N of a couple of mag 10.5 *s with which it forms a RA tri a few arc-mins away. Very small round 30" diameter halo, grows broadly and mod to centre without zones but with the suspicion of a very faint stellaring in the centre.

-17 is 7' SW and is fainter, very LSB small round halo maybe 20" diameter with a slight brightening to centre.

-39 is 15' E of -25 and is a threshold spot not much bigger than stellar of gossamer with no apparent central brightening.

P.A.: 77 Inclination: --- R.V.: +6263 Source: RC3 *

This is a small oval elong eg in about PA 75 which points almost at a mag 12 * about 2' away. Oval, 40" x 20" growing broadly and slightly to centre where there is a whiff of a slightly brighter spot. Fairly LSB.



x185 27' TF

NGC 3428 Galaxy *
RA: 10h 51m 29.5s Dec: +09° 16' 46"

P.A.: 170 Inclination: 6 R.V.: +7953 Source: RC3 *

This eg is found 4' NE of a 7th mag * which is very distracting. Seems to be elong in PA 15, 40" x 20" and grows slightly to the centre where there is a sub-stellar spot-type nucleus.



x185 27' TF

NGC 3426 Galaxy *
RA: 10h 51m 41.6s Dec: +18° 28' 50"
Mag: 14.1 (P) S.B.: --- B-V: --- Size: 1.2'x0.9' Class: S?
P.A.: 118 Inclination: --- R.V.: +6109 Source: RC3 *

This eg forms a small long S tri with a couple of mag 12 *s to its N by a few arc-mins. Round, mod SB small 40-50" diameter growing broadly and moderately to the centre where there is a small slightly brighter spot-type core nucleus.



x185 27' TF

NGC 3434 Galaxy *
RA: 10h 51m 57.9s Dec: +03° 47' 34"
Mag: 12.9 (P) S.B.: --- B-V: --- Size: 2.1'x1.8' Class: SA(r)b
P.A.: 5 Inclination: 1 R.V.: +3632 Source: RC3 *

This eg is found to the SW of a 13th mag * by only 2' away. Small, fairly small, round or slightly elong in PA 150 oval 50" x 40" grows slightly and broadly to the centre where there is a faint spot or stellaring.

IC 653 Galaxy *
RA: 10h 52m 06.8s Dec: -00° 33' 39"
Mag: 13.8 (P) S.B.: --- B-V: --- Size: 2.0'x0.8' Class: S0/a:
P.A.: 55 Inclination: 5 R.V.: +5538 Source: RC3

This eg forms a small RA tri with mag 13.5 *s to the S and W about 2' away. Seems elong in PA 60 as a small oval glow about 1' x 30" growing broadly and slightly to the centre where there is a good size slightly brighter core zone but no nucleus.

NGC 3438 Galaxy *
RA: 10h 52m 26.0s Dec: +10° 32' 51"

PGC 32636 Galaxy *
RA: 10h 52m 28.9s Dec: +10° 29' 20"
Mag: 15.5 S.B.: --- B-V: --- Size: 0.4'x0.3' Class: S
P.A.: 34 Inclination: --- R.V.: --- Source: PGC *

These two are both very small very faint spots of haze N - S of each other separated but about 3'. Each are about 20" diameter. -38 is probably slightly the brighter and larger and grows slightly to centre. It also has a mag 13.5* a little outside the halo to the E. -36 has a mag 14 * superimposed that dominates it. It is at best 15" diameter and no visible central brightening.

NGC 3441 Galaxy *
RA: 10h 52m 31.0s Dec: +07° 13' 31"
Mag: 14.5 (P) S.B.: --- B-V: --- Size: 0.8'x0.4' Class: S?
P.A.: 8 Inclination: 5 R.V.: +6659 Source: RC3 *

This eg forms a small RA tri with 2 *s to the E and SE mags 9 & 11. Fairly small and round, diffuse looking glow about 30" dia growing broadly and slightly to centre where there is a faint stellaring. Not far off the halo to the NE is a mag 14 *.



x185 27' TF

NGC 3444 Galaxy *
RA: 10h 52m 59.3s Dec: +10° 12' 36"
Mag: 15.5 (P) S.B.: --- B-V: --- Size: 1.1'x0.1' Class: Sbc: sp
P.A.: 19 Inclination: 7 R.V.: --- Source: RC3 *

This is a very tiny and extremely faint eg just N of a small tri of mag 13.5*s. Very, very tiny spot of haze, occasionally visible 15" diameter at best hard to see any other structure.



x185 27' TF

NGC 3462 Galaxy *
RA: 10h 55m 21.0s Dec: +07° 41' 49"
Mag: 13.2 (P) S.B.: --- B-V: --- Size: 1.7'x1.2' Class: S0:
P.A.: 60 Inclination: --- R.V.: --- Source: RC3 *

This eg makes a tri with *s to the E and SE, equidistant about 8' mags 8 & 10. Fairly small diffuse looking object with a prominent core/nucleus. 1' diameter grows evenly and slightly to centre where there is a small mod brighter core zone containing a sub-stellar spot.

NGC 3466 Galaxy *
RA: 10h 56m 15.5s Dec: +09° 45' 16"

NGC 3467 Galaxy *
RA: 10h 56m 44.0s Dec: +09° 45' 33"
Mag: 14.4 (B) S.B.: --- -V: +0.99 Size: 0.9'x0.8' Class: S0
P.A.: 31 Inclination: 1 R.V.: +9477 Source: RC3 *

MCG +2-28-29 PGC 32887 Galaxy *
RA: 10h 56m 33.0s Dec: +09° 56' 02"
Mag: 14.6 S.B.: --- B-V: --- Size: 1.0'x0.7' Class: Sab
P.A.: 167 Inclination: --- R.V.: --- Source: PGC *

The two NGC objects are aligned E - W about 5' apart. The two form a long flat E-W tri with a mag 11 * between them and a little to the N. Look very similar, round 30" diameter growing slightly to centre and at centre of each is a small, faint stellaring.

MCG +2-28-29 is N of that mag 11 * by 9' as a very small and faint LSB spot of gossamer about 30" diameter with no discernable central brightening and no core or nucleus evident.
