Steve's Notes
=====
NGC 6255
24" (6/12/15): at 375x; fairly faint, moderately large, very elongated 3:1 E-W, 1.5'x0.6', low but uneven surface brightness. At the east end of the galaxy is either a blue dwarf companion (HS 1653+3634) or more likely an intensely active star forming complex. At 375x it appeared as a very small, nearly stellar knot, just off the east end of the main glow. The knot had a higher surface brightness than the main galaxy.
17.5" (7/1/89): very faint, moderately large, very diffuse, low even surface brightness, elongated 5:2 E-W. A mag 14 star is off the south edge 1.8' from the center.
