The BGO robot imaged NGC 1931 for me. An open cluster with some nebulosity in Auriga. One of the RASC Finest NGCs. Some say it is a miniature version of the Great Orion Nebula. Unfortunately, there are a number of problems with the data. I'll have to reshoot.
Luminance only, 30 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; left is east.
The bright stars in the centre of the open cluster are a multi-star system, HJ 367. A is the bright member to the bottom-left or south-east. South-west is B which is slightly dimmer. To the north-west is C, dimmer still. D is not split cleanly in this poor image; it is merged with B, oriented to the north-west. North-east of the whole group is the dimmest of the five, the E star.
Due south of the cluster and nebula are some bright stars including NSV 2053.
To the south-west is some very faint nebulosity. This is Parsamian 28.

Tried to get more data on 11 Dec '16. Received more data on 21 Dec '16.
