NGC 2281: A Diamond in Auriga

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.

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.
