Description

Thor's Helmet in HSO. This nebula is an emission nebula about 11,960 light years away in Canis Major. At its center is a Wolf -Rayet star which is an extremely hot star in the later stages of its life which may go supernova some time soon.

I don't know why but a very dim area of nebulosity caught my interest in the upper left corner of the image just to the right of a bright red star. i can't find any reference to it so if anyone knows what it is, i would be most appreciative.

Description: I posted the original image far too early and, after constructive comments, decided to give it another go, this time using DBE and changing the orientation to the way it came out of the camera. Much happier with the result. I hope you agree.
