Quick update after yesterdays post.
NGC7293 Bicolour Helix Nebula
In all there is about 9 hours of data, split fairly evenly between Oiii and Ha captured between last year and this year.
In this version I added HA into the Oiii for Green and blue to get more detail and backed off on noise reduction. Then there may have been a bit of fiddling about with curves :-)
I cropped heavily. Whilst I have captured the outer areas I wanted to compose this with the focus on the core of the planetary neb. It stood up to the crop quite well.
Thanks for looking. Time to move on
