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.
