About this image

Peter reports that after almost two months of poor skies over Cornwall he captured this image of NGC1931 in Auriga, on 2019, January 9.  Exposure was 24x600s light frames with camera TEC at -15C; 32x flat frames; 32x600s dark frames; 100x bias frames.

NGC 1931, is an emission and reflection nebula in the constellation of Auriga and has been referred to as a "miniature version of the Orion Nebula", as it shares some of the same characteristics. There is a smaller version of M42's "Trapezium" in the hot, young star cluster in the centre of the emission nebula. It is about 3 arcmins in size and is estimated to be about 7,000 light years from Earth.
