Image obtained 12-13-2015 through RVO's Megrez 80mm refractor with Orion field-flattener lens, using a Baader-modified Canon XSi DSLR and BackyardEOS image-acquisition software – 18 (of ~30 obtained) carefully selected and stacked 360-second luminance frames combined with multiple dark, flat and bias calibration frames shot at ISO 1600 and totaling more than 300 minutes (~108 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 an Orion SSG3 Monochrome CCD camera using Maxim DL Pro and post-processed with DeepSkyStacker, Photoshop CS3 and NeatImage noise reduction software.
