While imaging M39 with my 135mm Rokinon, I noticed a familiar blob to the east in the frame. Re-centering brought the famous Cocoon, IC 5146, into view. I didn't know these two were that close to each other. Learn something new every day, that's what keeps you young. Anyway, Cocoon to the left and M39, that triangle of equal blue stars, to the right, both in a field of innumerable background stars and a blush of hydrogen.
