NGC 1931, found in the constellation Auriga has been referred to as a "miniature version of the Orion Nebula", as it shares some of the same characteristics. It is a mixed emission-reflection nebula, and contains a smaller version of the Trapezium in its hot young star cluster centered in the emission nebula. The entire cluster/nebula complex is only about 3 arcmin in size. The distance from earth is estimated at about 7000 light years.

Skies were clear but humidity varied from 60-87% which is really pretty high for a good imaging result. Click on the image for a closer view.
