Steve's Notes
=====
NGC 678
24" (8/30/16): fairly bright, large, very elongated 4:1 WSW-ENE, 2.5'x0.6'. Sharply concentrated with an unusually brighter core that is irregularly round, stellar nucleus. The arms are long and low surface brightness, but the warped dust lane was not seen. Forms a striking pair with NGC 680 5.5' ESE.
18" (11/22/03): fairly bright, moderately large, very elongated 7:2 WSW-ENE, 3.0'x0.8'. Sharply concentrated with a small bright core that increases to the center. The extensions are much fainter. Forms a pair with NGC 680 5' ESE in the NGC 697 group (also called the NGC 691 group).
13" (9/29/84): moderately bright, moderately large, bright core, elongated 3:1 ~E-W. Forms a pair with NGC 680 5' ESE in the NGC 697 group.
