17.5": very bright, large, elongated 2:1 WNW-ESE, 6'x3'.  There is a faint outer 
extension to the WNW (outer spiral arms?) which reaches extremely close to mag 
8.7 SAO 44530 just 3.7' from the center.

13" (5/26/84): very bright, elongated NNW-SSE, broad moderate concentration, 
stellar nucleus.  The southern edge is more sharply defined while the northern 
side is more diffuse and extensive.  A mag 8.5 star is off the NW edge.
