This object is one of the few star clusters in the sky that I have found interesting enough to photograph over the years, and this one is a cut above anything I ever did with film. This rich but very faint object lies within the outer stars of M35 near the foot of Gemini, and is 10 times more distant. It is its great distance that gives the cluster a rich yellow coloration from interstellar reddening from dust. The cluster is rated at 8.6th magnitude, and 5 arcmins in size.
