M42 done with the CanonEOSII 6D 'stock-new 2017 model' using a Baader 7nm HydrogenAlpha 2in. filter with an APM Flattener thru a 152mm A+M Refractor(OfficinaStellare) …last February . The first image is 3-CR2.s for 61secISO1600 which I think that ISO1600 is showing too much 'banding' lines in the images and I think ISO2500 will be better for regular imaging even with Broadband filters . The second image is 61secISO2500 and 11minISO6400 images for 12-CR2.s … The ISO2500 images were BiasMaster subtracted and the ISO6400 images were BaisMaster and DarkMaster subtracted …. and then I did the normal commands on each and Sum stacked them in MaximDL Pro V6.16 . Then I did a lot of other commands and it is the way it is … but the 'banding' doesn't show . The B33 HorseHead was 11minISO6400 for 2-CR2.s and BiasMaster and DarkMaster 'Calibrated' and then using "KernalFilter Median5x5" and the 'Low-Pass' filter and then the 'User-Defined' filter I made for more smoothing like on M42 for all the images in this message .x [ I tried to 'Calibrate' the CR2.s and nothing would happen … I counted the amount of 'BiasMasters and Darkmasters in the "Set Calibration" is about 26 different ones for a Canon 6D and Canon Rebel T7i ...so I 'un-checked' all the ones I didn't need and 'checked' the 6D Masters and then the 'light' frames would 'Calibrate' .]
