Steve's Notes
=====
NGC 3521
18" (5/14/07): very bright spiral with impressive structure, elongated at least 5:2 NNW-SSE, ~7.5'x3'. Contains a bright, elongated core highlighted by an intense, stellar nucleus. The halo is noticeably mottled at first glance and a dust lane runs NNW-SSE along the west side of the core. There is a strong impression of spiral structure with an arm attached on the east side that extends to the north and appears to curve towards the west in the outer halo. The halo appears more extensive or slightly brighter on the northern end. A more difficult arm appears to sweep to the south on the west side of the core.
17.5" (1/19/91): very bright, very large, elongated 5'x2' NNW-SSE. This is an impressive galaxy! Contains a well-defined small bright oval core NNW-SSE and a stellar nucleus. Appears mottled near the core and on the west side. Along the west side is a dust lane evident as a sharp light cut-off. The west side is somewhat fainter due to dust but extends beyond the dust lane.
8": fairly bright, fairly large, elongated, bright core. Located 33' E of a mag 6 star.
