x185 27' TF

NGC 3596 Galaxy *
RA: 11h 15m 06.2s Dec: +14 47' 13"
Mag: 12.0 (B) S.B.: --- B-V: --- Size: 3.9'x3.7' Class: SAB(rs)c
P.A.: 140 Inclination: 1 R.V.: +1176 Source: RC3 *

This is a mod bright eg, pretty large, about 2' diameter and round growing from very indistinct edges broadly and weakly to centre where there is a small slightly brighter round core zone and faint sub-stellar nucleus in the centre. It sits in a eq tri of mag 13, 13 & 14 *s about 5' a side.

NGC 3599 Galaxy *
RA: 11h 15m 27.0s Dec: +18 06' 37"
Mag: 12.0 (V) S.B.: 12.8 B-V: +0.87 Size: 2.7'x2.2' Class: SA0:
P.A.: 110 Inclination: --- R.V.: +781 Source: RC3 *

This is a pretty prominent, round pretty bright eg looking like an elliptical or SO type brightness profile. Maybe 1.5' diameter growing slightly and evenly to centre where there is a small slightly brighter core and a slightly brighter diffuse spot in the centre.

NGC 3559 Galaxy *
RA: 11h 10m 45.4s Dec: +12 00' 58"
Mag: 13.7 (P) S.B.: --- B-V: --- Size: 1.3'x0.8' Class: S pec
P.A.: 55 Inclination: --- R.V.: +3311 Source: RC3 *

There are no bright *s anywhere near this small eg. Toward the W side of the field there are many scattered mags 12.5-13.5 *s that look a little "cluster-like" Seems to be about in PA 45, an oval-shaped halo 1.25' x 30" growing broadly and slightly to centre without apparent core or nucleus. Reasonable SB.

IC 676 Galaxy *
RA: 11h 12m 39.7s Dec: +09 03' 23"
Mag: 12.8 (P) S.B.: --- B-V: --- Size: 2.4'x1.7'
Class: (R)SB(r)0+ P.A.: 10 Inclination: 3 R.V.: +1414 Source: RC3 *

This eg is located to the S of, and is almost pointed at by a line of mag 12 - 13.5 *s that I guess is about 7' long. Reasonable SB, about 1.25 to 1.5' x 30" in PA 0, brightening broadly and slightly to centre where there is a double core/condensation bright and almost touching about 10" diameter and slightly brighter than the halo.



x185 27' TF

NGC 3611 Galaxy *
RA: 11h 17m 30.1s Dec: +04 33' 21"
Mag: 12.8 (B) S.B.: --- B-V: +0.62 Size: 2.1'x1.7' Class: SA(s)a pec
P.A.: 32 Inclination: --- R.V.: +1754 Source: RC3 *

This eg appears about 3' due S of a mag 11 *. Easy to see, mod bright about 1.25' diameter, round growing at first slightly and broadly then nearer centre moderately to small somewhat brighter core zone and slightly brighter spot in the centre.



x185 27' TF

NGC 3630 Galaxy *
RA: 11h 20m 17.0s Dec: +02 57' 51"
Mag: 12.9 (P) S.B.: --- B-V: --- Size: 2.8'x1.1' Class: S0 sp
P.A.: 35 Inclination: 6 R.V.: +1509 Source: RC3 *

This eg is to the NW of a mag 8 * by about 13' and is pretty conspicuous object with a pretty "hard" looking, well-defined halo in PA 30, 1.5' x 10" , grows to the axis moderately, even in the outer halo and moderately to centre. At centre is a conspicuous bright spot type core/nucleus that is not quite stellar and about mag 13.5. Very pretty.

This is a lovely and very compact little Hickson group where it seems all 7 are visible, though 3 only very, very fantly. -51, -53 and MGC +4-37-30 are all small faint egs that form a RA Tri with the MCG eg at the RA and -53 southern most. The two NGC galaxies are about 30" diameter, round and about 30-40" diameter. -53 maybe weakly elong in PA 90 rising slightly to centre without zones. The MCG eg is a fraction smaller and fainter, maybe 20" diameter.

PGC 34899 is an almost stellar spot of haze appended to the southern edge of -51 while PGC 34901 is just E by 30-odd ". Both are no more than 10" diameter and very faint spots of gossamer.

IC 2759 is about 4' due W of this central group and is a little fainter that -53 and -51, about 30" x 20" in PA 0 brightening slightly to centre and contains a faint weakly brighter spot at centre. MCG +4-27-27 is just N of IC 2759 as a 15" diameter patch of very faint mist with no central brightening. All up the whole group is no more than 6' diameter.

P.A.: 72 Inclination: 6 R.V.: +2595 Source: RC3

This eg appears to the SW of a mag 10 * by about 5' and almost points at that star in PA45 as a reasonable SB but very small lens shaped halo about 40" x 10" growing broadly and mod to the centre azonally to the centre without apparent core or nucleus.

Mag: 13.7 (P) S.B.: --- B-V: --- Size: 1.4'x0.8' Class: SAB(r)bc pec
P.A.: 25 Inclination: --- R.V.: --- Source: RC3 *

This eg appears almost due N of a mag 12 + 14 pair had has a mag 13 superimposition * just NE of centre of its small oval-shaped halo, about 1' x 30" growing slightly to centre without nucleus. Difficult to assess with that distracting star any structure.

P.A.: 125 Inclination: --- R.V.: +1157 Source: RC3 *

This eg is pointed at by a mag 11 & 11.5 * which are away to the SE by a few arc-mins. Pretty small and faint eg about 30" diameter growing broadly and slightly to centre where there is a small weakly brighter spot.

These four egs are in a weakly curved line convex to the S about 15' long.
At the far W end is -53 whcih is barely S of a mag 10 * whcih is very distracting to the observation. Small, round halo maybe weakly elong in PA 0 about 30" diameter rising slightly to centre with a small weakly brighter 10" core zone.

-98 is at the E end and is pointed at from the SE by a couple of mag 11 *s. It is a very small oval halo of pretty LSB about 30" x 20" growing broadly and slightly to centre without nucleus. Between these to are from E to W -96 and -2857.

-696 is a very small, faint round spot about 30" diameter of LSB rising slightly to centre. -2857 is next about 3' further W as an extremely faint streak of gossamer 30" x 5" in PA 0 with no apparent central brightening.

IC 701 Arp 197 Multi-Galaxy Sys *
RA: 11h 31m 01.4s Dec: +20 28' 17"

P.A.: 44 Inclination: --- R.V.: +6182 Source: RC3 *

This is a very very small very LSB round eg making a RA Tri mag 10.5 *s to its E. Seems no more than 30" diameter, round growing broadly and weakly to centre azonally without core or nucleus.

Pt 11 to follow ...
