M35 and NGC2158 in Gemini

"Oh, my God! It's full of stars!"

Two apparent neighbor star clusters belong to the most attractive objects of the Gemini constellation. The small open cluster (NGC2158) is far behind the large one. The light of the 97 variable stars in NGC2158 needs almost 13000 years to reach the large open cluster (Messier 35) in the foreground.

Equipment: FSQ-106ED(f/5), Nikon d3100, Aperture(Mac), MaximDL. This photo is the result of three stacked, unguided exposures with 184+145+114 seconds.
