Description

This is a two panel mosaic of the Running Man nebula (NGC 1977) and De Mairan's (Messier 43. NGC 1982) nebula in Orion. These objects are to be found some 1,400 light years from Earth.

Data for this image was collected between 19 November 2020 and 16 January 2021 from a rig in Spain that is privately owned and operated by Barry Wilson and me.
