Description

Kinda fun and tough one to process because of all the surrounding dust.

One thing is for sure ... this is an object that would most certainly benefit from the added detail acquired by narrowband filters. I may have to go back and revisit this one with Ha and OIII in the future.

As always, thank you for taking the time to look and all comments/criticisms are welcome.

Revision B:
- due to some very much appreciated candid feedback (thank you; Adam, Jim and 'Ratter) I've gone back and brought the colours back to something a bit more *realistic*
- converted to LAB mode in PS and adjusted "b" channel
- rotated to a more familiar presentation

Rev C:
- increased depth and contrast
- slight colour boost to cover contrast change
