Description

Waaaay back in early April I started this project, and in my eagerness I was overly ambitious and tried shooting while the moon was up. The moon was so close to the object it was crazy - as were the resulting gradients from hell! Then I had my camera problem, so too late to reshoot after the QSI came back from the USA.

Seriously a nightmare to process, along with some minor tracking issues that meant I also had to repair the stars in Startools - anyway, this is no Malin Award winning image, but inspired by Slawomir's version I thought I might as well process it anyway using my newly learned Startools techniques.

Approx 15hrs data. 5hrs ea of HA, O3 & S2 in 15min subs.

Lesson learned, don't shoot DSO's next to the moon, esp with O3 filter!

Thanks for looking, comments welcome
