This is my second attempt at the Rosette with a new camera setup. The new QHY600 seems much more sensitive than my other past cameras, and I cant wait to continue to test this thing out! This was a total of just under 7 hours of exposure.

12 x 5 mins R, G, B

Processed in PI 1.8.8 and PS CC. Minor tweaks with a couple other programs.
