I used a 6" f/4 610mm focal length Newtonian, Canon T2i for imaging camera, AVX mount for tracking, ZWO ASI 120-M for guide camera (mounted to 50 mm guide-scope). About 64 300 second exposures at ISO 800, stacking in Deep Sky Stacker program (free) with bias, flats and dark frames included (these are called calibration frames). Final processing in PhotoShop CS6.
Great photo! I was a Astrophotographer a few years ago and know how difficult it is to photograph objects!
