Image obtained October 04-05, 2016 through RVO's Megrez 80mm refractor with Orion field-flattener lens, using a Baader-modified Canon XSi DSLR and BackyardEOS image-acquisition software – 24 carefully selected and stacked 300-second luminance frames combined with multiple dark, flat and bias calibration frames shot at ISO 1600 and totaling more than 270 minutes (~120 minutes effective luminance) were used to create this image; optics driven by the Losmandy G-11 mount equipped with Ovision's precision RA worm gear, guided with a ZWO ASI 120MM Monochrome CCD camera through a 60mm guidescope using PhD2 guiding software and post-processed with DeepSkyStacker and Photoshop CS3 s/w.
