NGC 2281 is an open star cluster in the constellation of Auriga. It’s best viewed during the late winter months into early spring.
You see the central stars make a diamond shape. Also, one will notice a mix of red and blue stars, which makes this relatively unknown cluster of 30-40 stars a worthy find.

Seattle, Washington, USA
Meade LX65 8″ ACF, 18mm eyepiece
Even though I know this cluster is larger than it looks based on my reading, NCG 2281 is only showing me a handful of prominent stars on this night due to fair seeing conditions at the moment. In the middle, I do notice the diamond asterism mentioned by other observers.
