Steve's Notes

===== NGC 1807 18" (1/26/09): this asterism contains a very faint galaxy, CGCG 469-003, located just following a 26" pair of mag 11.5/12 stars just south of center. The galaxy appeared very faint and small, round, 15" diameter, low surface brightness. 17.5" (2/1/92): bright, moderately large, striking group of 30 stars mag 9-14 in 12' including 10 stars mag 11 or brighter. Five bright stars are in a 11' string oriented N-S. The central star in this string is a pleasing, close double star h3268; consisting of mag 9.5/10.5 stars at 10" separation. This double is collinear with two mag 11 stars 1.3' E and 2.9' E oriented perpendicular to the string. Several other members trail to SW forming a cross asterism. 8": ~25 stars in cluster including 10-12 brighter stars, several almost collinear. A double star mag 10/11 at 10" separation is near the center. Forms a pair of open clusters with NGC 1817 25' NE.
