Andromeda Galaxy, M31
20 x 2-minute ISO 3200 exposures (taken last night) and 7 x 7-minute ISO 1600 exposures (taken 8 August 2015). Astro-modified Canon 600D and Sky-Watcher ED 80mm f/6.25 telescope, piggybacked on a Celestron C8 telescope for manual guiding.
Frames stacked in Deep Sky Stacker software. Result post-processed to increase contrast, reduce noise and adjust overall colour balance. I also used Noel Carboni's astronomy tools in Photoshop Elements to reduce the prominence of the stars (which otherwise dominate after stretching the contrast).
