17.5" (8/16/93): 40 stars mag 10-15 in 4' diameter.  Includes a rich 1.5' region 
with 15 stars with a nice triple star in a tight equilateral triangle.  Other 
brighter stars in this grouping form a pentagon outline.  Three equally spaced 
mag 9-10 stars oriented E-W begin just off the S side.  Several sprays of stars 
emanate out in various directions from the central region.

17.5" (11/2/91): fairly bright and compact, ~30 stars mag   9-14 at 220x in a 4' 
diameter, distinctive group.  Just N of center is a tight triple star with 4th 
star to E, also second trio of stars is close S.  A mag 9 star near the S edge 
is collinear with two mag 9 stars 2' SE and 4' SE all equally spaced.
