The Pinwheel Galaxy With Dithering and an LPR (ZWO mono)
Tonight I went after M101 (the Pinwheel galaxy) and used an LPR filter (in place of my luminance) and also dithered for the first time. Setting up 'dither' in Sequence Generator Pro was easy and I like the results. I will have to capture RGB data on another night. Here is more info:
