NGC2420 is a compact open cluster lying at 4 degrees east of delta Geminorum that forms the body of younger brother of the twins, Pollux.
The cluster has 10-arc minutes diameter and 8th magnitude, contains about 100 fine member stars.
The stellar density of NGC2420 is fairly high, it looks like a dimmed nebula with binoculars.
And you can enjoy several bright stars scattered in front of the nebulous faint light of other stars through telescopes with an aperture of about 3 to 4 inches or so.
It is certain that the cluster compares unfavorably with a major open cluster of M35 in Gemini,
but it may give you great interest to compare these clusters in winter skies.
