NGC 436
24" (1/4/14): at 200x, ~50 stars are resolved in a rich, 4' group that is well-detached and distinctive. The main group is confined within a triangular outline with a mag 10.9 star at the S end, a mag 12 star at the W end and a mag 11.5 star at the N end. Contains a very rich central region ~1.5' diameter and includes STI 1550, a close triple with components 11.2/11.3/11.8 at 9" and 12". Another uncatalogued pair is just 0.6' S of STI 1550. Two mag 9.5/10 stars are collinear to the east of the mag 10.9 star at the south end.
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 south 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 north of center is a tight triple star with 4th star to E, also second trio of stars is close south. A mag 9 star near the south edge is collinear with two mag 9 stars 2' SE and 4' SE all equally spaced.
