x185 27' TF

NGC 3166 Multi-Galaxy Sys *

NGC 3165 Galaxy *
RA: 10h 13m 31.4s Dec: +03 22' 32"
Mag: 14.5 (B) S.B.: --- B-V: +0.63

-66 and -69 are both very bright egs, -66 is in the centre and -69 is 7' distant in PA 75 while --65 is about 5' in PA 225. -66 and -69 are both very bright and large Egs with very good SB -66 would be maybe 2.25 x 1.75' in PA 75 with very faint edges rising broadly and mod to centre with a small, compact core zone elong in the same PA about 20" diameter that is considerably brighter than the halo and contains a brighter stellaring at centre.

-69 has a less conspicuous core/nucleus and is overall of lower SB but still elong in PA 45, 2.25' x 2 growing broadly and mod to centre from very diffuse edges and contains a considerably brighter higher SB core zone 15" diameter that is much brighter than halo.

-65 is a much smaller and fainter eg, considerably fainter, elong in about PA 160, 1' x 40" no evident core or nucleus, brightening broadly and weakly to centre.

IC 599 Galaxy *
RA: 10h 13m 12.4s Dec: -05 37' 45"
Mag: 14.5 S.B.: --- B-V: ---
Size: 1.1'x0.2' Class: Sbc P.A.: 36
Inclination: --- R.V.: --- Source: PGC *

This is a very faint and small eg took a while to pick up Seems to be weakly elong in PA 0, 40" x 30" growing azonally, weakly and broadly to the centre with a small round slightly brighter core zone at centre with no apparent nucleus. No *s associated.



x185 27' TF

NGC 3156 Galaxy *
RA: 10h 12m 41.3s Dec: +03 07' 46"
Mag: 13.1 (B) S.B.: 12.0 B-V: +0.77
Size: 2.2'x1.0' Class: S0: P.A.: 52
Inclination: 4 R.V.: +1118

This eg is quite close to a very distracting tri of mag 7, 8, & 9 *s of which the hypotenuse points straight at the eg. It seems in PA 45, good S>B 1.25' x 40" growing from indistinct edges broadly and slightly to the centre but at centre is a pretty well defined small core-zone that contains a very faint stellaring.

IC 590 Multi-Galaxy Sys *
RA: 10h 05m 50.5s Dec: +00 38' 00"
Mag: 14.2 S.B.: --- B-V: ---
Size: 0.9'x0.5' Class: E P.A.: 170
Inclination: --- R.V.: +6317 Source: PGC *

MCG +0-26-16 Galaxy *
RA: 10h 05m 24.1s Dec: +00 32' 37"
Mag: 15.0 S.B.: --- B-V: ---
Size: 1.1'x0.3' Class: S0/a
P.A.: 113 Inclination: --- R.V.: --- Source: PGC *

These two look quite strange in the field together, they both seem elong in PA 120 and both have a nearby star that is on axis -90 to the W and -16 to the E of the same brightness and at the same distance -- to that extent they look mirror-imaged. IC 590 is NE of the MCG eg and they are separated by about 10'.

-90 is elong in PA 120, about 50" x 20" with a mag 13 * to the WNW by 1.5'. Seems to have a weakly brighter broad streak through it.

-16 has a mag 13* at the opposite end about 40" x 20" with lower SB brightening weakly to the axis near centre but having no zones or apparent nucleus. Weak SB fairly faint.

NGC 3117 Galaxy *
RA: 10h 06m 10.5s Dec: +02 54' 46"
Mag: 14.3 (P) S.B.: --- B-V: ---
Size: 0.8' Class: E? P.A.: ---

This is a pretty non-descript small round eg found to the N of a faint pair mags 12 + 14 which is to the S of the eg by 10', small lowish SB 40" diameter growing broadly and slightly to centre with no evidence of zones but occasionally there is a glimpse of a faint stellaring near centre.



x185 27' TF

NGC 3142 Galaxy *
RA: 10h 10m 06.4s Dec: -08 28' 48"
Mag: 14.1 S.B.: --- B-V: ---
Size: 1.0'x1.0' Class: S0
P.A.: --- Inclination: --- R.V.: --- Source: PGC *

This eg is found to the S from a distracting mag 6* which is a bit of a pain. Seems round, mod bright considering the distraction, a bit over 1' diameter rising broadly and slightly to centre where there is a somewhat brighter round, well-defined core/nucleus.



x185 27' TF

IC 592 Galaxy *
RA: 10h 07m 58.8s Dec: -02 29' 53"
Mag: 14.2 (P) S.B.: --- B-V: ---
Size: 0.8'x0.8' Class: Sbc P.A.: ---
Inclination: --- R.V.: +5976

IC 593 Galaxy *
RA: 10h 08m 17.8s Dec: -02 31' 36"
Mag: 14.5 (P) S.B.: --- B-V: ---
Size: 0.7'x0.5' Class: S? P.A.: ---
Inclination: --- R.V.: +5970 Source: RC3 *

These two egs are near a mag 8 * that is yellowish. -92 to the N by 3', -93 to the E by 5'. -92 is a very LSB diffuse haze that is only visible with AV. Difficult to establish size, maybe 1' diameter with no apparent central brightening.

-93 is a little brighter than -92, seems to be round and have better SB. Round, about 40" diameter growing slightly to the centre without core or nucleus apparent.



x185 27' TF

IC 594 Galaxy *
RA: 10h 08m 31.9s Dec: -00 40' 00"
Mag: 14.6 (P) S.B.: --- B-V: ---
Size: 1.0'x0.5' Class: SB(r)bc P.A.: 127
Inclination: 5 R.V.: +6409 Source: RC3

This eg is found to the S of a mag 10 * by 4' as a very small diffuse, LSB fairly faint patch of haze with no real structure visible brightening weakly to centre, no core or zones apparent.

Pt 3 to follow ...
