V = 12.9;  Size 24"x21"

17.5" (5/27/00): fairly bright, fairly small, slightly elongated NNW-SSE, 
25"x20".  Contains an easy mag 13.5 central star which stands out well at all 
powers.  At 380x, the halo appears to brighten surrounding the central star.  
Nicely framed within a triangle of mag 9-10 stars.

17.5" (5/30/92): fairly bright, small, 20" diameter.  A bright mag 13 central 
star is easily visible.  Located within a bright isosceles triangle consisting 
of mag 8.8 SAO 45874 4.8' NW, mag 8.7 SAO 45881 6.3' NE and a mag 10 star 3.5' 
S.

8": at 100x, faint, very small, round, even surface brightness.  At 200x, an 
extremely faint mag 13.5-14 central star is visible surrounded by a small faint 
halo.  Two mag 9 stars to the north form an rough isosceles triangle.
