Nebulae in Monoceros


This image was taken on Monday evening and although it was taken at primefocus (750mm f/5) I would call it a widefield view of the S-Mon nebulous region. Clearly visible is the nebulous cluster surrounding S-Monoceros itself (top of the frame) predominantly bluish in colour here - NGC2264.
To the centre of the image you can just pick out the faint red nebula referred to as the Cone Nebula.
And to the extreme right of the image you can see Hubble's Variable Nebula - NGC2261. The nebula reflects light from the irregular variable star R Mon and hence changes shape and brightness over a matter of weeks.
