Steve's Notes
=====
NGC 3104
17.5" (4/18/98): faint, moderately large, ~1.5'-2' diameter although seems irregular in shape. Appears as a low but irregular surface brightness glow with a mag 13 star embedded at the south edge. Unusual appearance and could be mistaken for a reflection nebula around the star. With averted vision a fainter outer halo "grows" at times to 2.5' diameter nearly to a mag 14 star off the NE edge.
