The double star is in the upper left arm of Cancer, and although Cancer is itself a fairly dim constellation, this makes it an easy target to spot. The two stars are supposed to appear yellow and blue/white in a scope, but in my camera they came out more red and blue.

I used the same stacked-background single frame insert technique that I used on 8 Lacertae and I'm pleased with the results again!
