NGC2420 is an open cluster in Gemini. It is not among the most popular targets since it is neither particularly impressive nor really challenging. However, I find it one of the better clusters in Gemini, and well worth a look. It is located just a few degrees east and slightly north of the Eskimo nebula, and I usually visit the cluster every time I observe the famous planetary.
I usually observe this cluster at low magnification. It appears moderately compressed and rich at 30 - 50x power with 6 - 8 inches of aperture. It is the first entry in Herchels catalogue #6.
