17.5" (2/2/02): immediately picked up at 100x as a very small, bluish-gray "egg" 
of fairly high surface brightness.  Good contrast gain with OIII filter.  At 
380x (unfiltered), it appeared as fairly bright, clearly elongated SSW-NNE, 
~27"x20".  The surface brightness was irregular or mottled with a slightly 
brighter rim and darker center giving a weakly annular appearance.  The rim 
seems to have a couple of slightly brighter spots and the ends of the minor axis 
are slightly dimmer.  No sign of a central star.

17.5" (12/8/90): fairly bright, slightly elongated 4:3 ~SSW-NNE, about 30" 
diameter.  Appears slightly annular at 412x with a brighter rim.  No central 
star seen at this power.

13": moderately bright, high surface brightness.   No internal structure was 
visible.
