The Rosette Nebula (NGC2237) lies 5000 light years away in the constellation of Monoceros.
It's a star forming region, the cluster of stars in the centre having been formed from the gas clouds of the nebula. This stunning image was captured by Martin Baker, a member of Guildford Astronomical Society. He used a small (72 mm) refractor telescope, a motorised tracking mount and a specialised astro-imaging camera.

About 30 separate exposures (some of 15 minutes in length) were taken using three different filters in January 2017. These images were combined using software then processed to give this splendid result.
