An experiment to see how long I could expose for! 3x10min exposures. Some RA wiggle is noticable, and some possible optical distortion in the lower right. This was taken in twilight - the nebula was only slightly brighter than the sky. My first impression was "what a lot of stars!". Some flat fielding could also be useful.

Captured in Artemiscapture. Stacked in Registax, co-registered and scaled in IRIS, finally processing in photoshop.
