Corwin's Notes
=====
NGC 5256. There is no indication that either WH or JH saw this as a double
nebula. So, I've adopted the mean position of the two galaxies as that for
the NGC object.
The northeastern object, perhaps a bit brighter, is Markarian 0266 and a
Seyfert galaxy with broad and strong emission lines.
Steve's Notes
=====
NGC 5256
24" (6/4/16): at 322x; fairly faint to moderately bright, fairly small, elongated 4:3 SW-NE, 40"x30", brighter ill-defined core, uneven surface brightness. Occasionally, a brighter quasi-stellar knot (nucleus of the merged companion) would pop on the northeast end of the glow [nuclei separated by just 10"!] HJ 2667, a wide pair (14") of mag 11 stars, lies 5.6' WSW.
17.5" (5/11/02): fairly faint, fairly small, slightly elongated SW-NE, 0.8'x0.6', irregular surface brightness. A mag 15 star is 1.0' NW of center. Located 5.5' ENE of an evenly matched pair (HJ 2667) of mag 11 stars at 14" separation.
This is a well-studied merging system consisting of a Seyfert 2 and a LINER galaxy with compact nuclei separated by just 10".
