Steve's Notes
=====
NGC 4839
17.5" (5/14/94): fairly faint, fairly small, elongated 3:2 WSW-ENE, 1.0'x0.7', weak even concentration to a brighter core. Lies exactly midway between a mag 11.5 star 2.5' NE and a mag 14 star 2.4' SW. Forms a close pair with NGC 4842 (double system) 2.6' E. In the field are NGC 4840 7.0' N and MCG +05-31-023 3.8' SW. An anonymous galaxy was picked up 11.4' WNW. This member of AGC 1656 is a double system with a companion superimposed 0.4' SW of center (not resolved).
