NGC/IC Objects

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 whereas 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. About 7' due south, a pair of 10th and 11th magnitude GSC stars stand separated by an arc minute. About 4' due east of this pair, another double is visible. This pairing includes 11th and 12th magnitude stars about 36" apart. Another 13 field stars complete the view.
