NGC 1931: Open Cluster & Nebula (Auriga) RA: 05h 31.4m / DEC: +34° 14'.7
Instrument: 10-inch Starfinder

This delicate tandem lives in the same neighborhood as a pair of bright Messier clusters, M36 and M37. M36 resides 1 degree due east. M37 is a little further down the block at 1.7 degrees to the northwest. The sketch at left presents NGC 1931 as it appears in my 10-inch Newtonian at 129X. A delicate oval nebulosity wraps 12th magnitude GSC 2411:1686 just north of center. This misty patch extends northeast-to-southwest over a 4'x2' area. Of the 17 stars dotting the field, only the two 11th magnitude embers just west of the nebula are cluster members.
