Description:
[Following] are observations of the four best Shakhbazians I've viewed...
Another one to take a look at is Shkh 26 = Abell 1143. If these prove easy
for the large aperture crowd, take a look at Shkh 49, located just 20' NW
of the N3158 cluster!  -Steve Gottlieb

Shkh 30 = HCG 97 (4 galaxy members)

IC 5357 = M-01-60-033 = HCG 97a = Shkh 30-1
23 47 22.9 -02 18 02    V = 12.9    Size 1.7x1.1    SB = 13.5    PA 35deg
(9/3/94): brightest of four IC galaxies in HCG 97 = Shakh 30.  Faint,
small, elongated 3:2 NW-SE, 0.7'x0.4', gradually brightens to a small
bright core and an almost stellar nucleus.  A mag 11 star (with IC 5351
attached) is 2' SW.  IC 5351 lies 1.3' SW, IC 5356 3.0' S and IC 5359
3.8' ESE. IC 5352 = HCG 97E not seen.
(10/21/95): faint, fairly small, elongated 4:3 NNW-SSE.
--
IC 5351 = M-01-60-032 = HCG 97d = Shkh 30-2
23 47 18.9 -02 18 50    V = 13.6
(9/3/94): this is the third brightest galaxy in HCG 97 group.
Extremely faint, extremely small, round, 10" diameter.  Attached at
the N side of a mag 11 star which makes viewing very difficult.
Located 1.3' SW of IC 5357.  IC 5356 lies 2.5' SE and IC 5359 is
4.7' E.
(10/21/95): extremely faint, extremely small, round.  Attached at the
N side of a mag 12 star which detracts from viewing.
--
IC 5356 = M-01-60-034 = HCG 97c =  = Shkh 30-3
23 47 23.8 -02 21 04    V = 14.0
(9/3/94): second brightest galaxy in HCG 97 group.  Very faint, very
small, slightly elongated (although difficult to pin down direction),
very weak concentration.  Located between two mag 14 stars off the SW
and NE ends and 3.0' due S of IC 5357.  Forms the southern vertex of
an isosceles triangle with a mag 11 star 2.5' NW and a mag 10 star
2.6' NE. IC 5351 lies 2.5' NW and IC 5359 is 4.0' NE.
(10/21/95): very faint, small, round.  A mag 14.5 star is 45" SSW.
--
IC 5359 = M-01-60-036 = HCG 97B = Shkh 30-5
23 47 37.9 -02 19 00    V = 14.7    Size 1.1x0.2    SB = 12.8
Faintest of four galaxies in HCG 97 compact group.  Extremely faint,
small, very elongated 4:1 NW-SE.  Only visible with averted vision and
cannot be held steadily.  Located 1.6' ENE of a mag 10 star which also
detracts from viewing.  Last in group with IC 5351 4.7' W, IC 5357 3.8'
WNW and IC 5356 4' SW.
