Object - Located in the constellation of Monoceros at a distance of 5200 light years. It is around 130 light years in diameter and contains a bright cluster of hot stars which are causing the emission nebula to glow.
Imaging note:- I suspect that the halos around the brighter stars are caused from reflections with my Astronomiks Ha filter. Each sub frame contained the reflection at the same intensity.
