This image replaces an earlier capture of the same object.
Astro-modded EOS 600D,Canon EF 70-300mm f/4-5.6L IS USM 39 x 7-minute ISO 3200 exposures at f/7.1, taken over 2 nights. Lens at 300mm piggybacked on a Celestron C8 telescope for auto-guiding.
Frames stacked in Deep Sky Stacker software. Result post-processed to increase contrast, and to reduce noise and colour gradients caused by light pollution.
I also used Starnet++ to temporarily remove the stars (which otherwise dominate after stretching the contrast).
