About this image

As others have noted this is a difficult target and required a lot of processing in PixInsight. In order to emphasise the nebulosity I have de-emphasised the star field and have a lot of unnatural colours in the stars. However, I was pleased to see the strong Oiii and Halpha portions of the nebula. The data was acquired over two consecutive nights
