M35 is a young (100 to 150 million years) open cluster in Gemini at a distance between 2700 and 3600 light years. It has an estimated 20 stars down to 10th magnitude, 120 down to 13th magnitude and an amazing 2,700 down to 21st magnitude.

To the upper right is the faint very compact, rich NGC 2158 open cluster at an estimated distance of 12,000 light years. Its calculated age of two thousand millions years make it potentially one of the oldest open clusters in the Milky Way.
