Dragon's Egg Nebula in HSO
This emission nebula energised by the central O-type star, is an unusual object. It was surprisingly difficult to bring out the fainter details in Photoshop despite trying various techniques like channel masks and Lab colours. In the end I just used the more usual selected colour masks.
