APOD 3.2

Kemble's Cascade
http://apod.nasa.gov/apod/ap100128.html

Kemble's Cascade is an asterism, which is a pattern or shape in the stars that is not an actual constellation. This asterism includes around twenty stars that are nearly in a line. It is in the constellation Camelopardalis, and spans more than five full moon diameters. It was named recently; Lucian Kemble, an amateur astronomer, described it to Walter Scott Houston, who wrote about it in his magazine column in 1980, naming it "Kemble's Cascade." Also visible in this picture is NGC 1502, an open cluster of about 45 stars. Two Struve binary stars are present in NGC 1502.
