Notes:

This rich open cluster is situated at the northern portion of a large (150' x 60') streamer of nebulosity called IC 2177, Sh2-292, LBN 1027, etc; also known as the "Seagull" or "Eagle" nebula. This large complex contains several more open clusters and named nebulous sections, well worth imaging in years to come.

According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of this open cluster is 7.0 arc minutes.

17.5": 50-60 stars mag 10.5-14 in a 10' diameter.  Mag 6.9 SAO 134220 is 10' NE 
of the core.  In the center is a 1' parallelogram formed by four mag 10.5-12 
stars with parallel sides oriented E-W and NW-SE.  There are no dense areas 
(overall fairly scattered appearance) although includes several subgroups.  A 
wide mag 12 double is on the N side.  Located at the N tip of the huge emission 
nebula IC 2177.
