Description

Witches head nebula

This was a tough one for me. Lots of noise and gradient problems with the lights.

I processed the stars down a little to bring out the nebulosity (PS). I also reduced the colours to give it a classic cast.

This is also heavily cropped.

Any and all comments are always welcome.
