Description: ABELL 1656 east core. The brightest galaxy in the
field is NGC 4889. 
NGC 4889 (11.5m(v), 2.9'x1.9', E4+, Br3): Slightly elliptical
(1,2:1) WSW-ENE. Moderately concentrated, no core. 

NGC 4886 (13.8m(v), 1.1', E0, Br4) is the stellar point W of the
core of NGC 4889. Suprisingly easy. 

NGC 4883 (14.3m(v), -, SB0, Br5): Between -89 and a mag. 7 star
on the W edge. Very faint but easily seen. Very small, about
15''. Shape indefinite. Slightly concentrated. 

NGC 4907 (13.5m(v), 1.2'x1.0', SB(r)b, Br4): is the galaxy
included in 'outer space' aka outside the circle. Round. Has
even surface brightness and quite sharp edges. Could be a
planetary nebula. Very close to a mag. 13 star. 

The faint stellar object slightly outside the circle near -07.
is either the mag. 15.7 compact galaxy CGCG 160-251 or a nearby
mag. 15 field star. Who knows...

N of NGC 4889 is IC 4021 (14.8m(v), 0.4'x0.4', E, Br5): Very
faint, very small (10''). Non-stellar.

E of NGC 4889 is a quite bright stellar galaxy, NGC 4898
(13.5m(v), -, Ep, Br4)

The only object near visible in photographs the stellar point
drawn ENE of NGC 4898 is PGC44763 (15.4m(v),-,-,Br5). ???

Following the line of the two stellar galaxies (-98 and the PGC
galaxy) towards E the next galaxy visible is NGC4906
(14.1m(v), -, E3, Br5): A mag. 14 star with some fuzz around it,
mostly on the NE-E side. Photographs show a star and a galaxy.

The triangle of galaxies N of NGC 4907: The W-most (the one with
a stellar nucleus is IC 4041 (14.3m(v), 0.7', E6, Br5): An
extremely small glow around a mag. 14.5 star. This is also a
star+galaxy pair in photographs.

E of IC 4041 is IC 4051 (13.2m(v), 1.0'x0.9', E0, Br5): Slightly
smaller than NGC 4908 (below) but very similar. Round. 

The last galaxy (N of IC4051) is NGC 4908 (13.5m(v), 1.1'x0.9',
E5, Br5): Slightly elliptical, not concentrated. Difficult. Size
about 35''x30''.
