Steve's Notes

===== NGC 2422 18" (3/2/08): this naked-eye cluster is stunning at 73x (31 Nagler), though at 30' diameter is too spread out for higher powers. The stars are arranged in beautiful chains and groups. The brightest half-dozen stars are in a 10' subgroup in the center including a striking white double star (·1121 = 7.0/7.3 at 7") that is is surrounded by many stars in chains and loops. The brightest star on the west side is a wide, unequal double (5.7/9.7 at 20"). Perhaps 200 stars are scattered around at low power. 13.1" (11/5/83): very bright, very large, fairly rich, impressive. Includes double stars ·1121 = 7.9/7.9 at 7" in the center and ·1120 = 5.7/9.6 at 20" on the west side. Easy naked-eye object in a dark sky. 8": very bright, large but scattered, includes ·1121 = 8/8 at 7" near core and ·1120 on west side, many colored stars.
