    I didn't do too much to this image except "ColorBalance" and "Curves …?? so it can be worked on... it's 12BIT 4095 but saved as 16BIT .x

    152mm A+M Refractor(OfficinaStellare-1200mmFL) using an APM Flattener and a BreakThrough X4-UV 49mm filter with step-rings from 35mm T-Ring to APM Flattener step-rings and using a CanonEOSII RebelT7i 'modified UV-IR @ Hutech' on an Astro-Physics 1200GTO Mount at 1xSiderealGuideRate and doing 30secISO6400-12800 RAWMonochrome Bin1 Autosave images in MaximDL Pro V6.20 for thirtyfive ISO6400 images and thirtyfive ISO12800 images ; and a good idea is to list the ISO# in the 'suffix' box by the exposure time box so you can tell which images are which to move them to their own Folder when you go to process them , or you'l have to 'open' them in MaximDL Pro and see what they are with the FITS Header window which is real time consuming to do sixty or more Autosave images . . I did a Calibrate using a FlatMaster that was done with a Pink shirt from Wal-Mart to cover the Aperature because an Internet page said Pink gets Red_Green_Blue better than White ..for the 'flats' at ' .05sec ' for each ISO for two frames each ... and then other commands in a BatchProcess and I saved them as IEEEFloat to eliminate line streaks . I stacked each separate ISO as Average in their own Folder and then I used the stacked FITS of each ISO and then stacked them as Sum ... all images and the FITS were "PinPointAstrometry" 'GSC solved' . I used the "ColorBalance - Scaling 300% for 'Red' , 'Green' , and 'Blue' and Auto-Background button" on the finished FITS A21 image . Then other commands like "Curves-Luminance" two times and "Deconvolve - ' 2.0 e/ADU ' and Gaussian and MaximumEntropy 30 Iterations , then 'screen-stretch' to darken and to lighten and then the "KernalFilter - sequence of HighPassMore to LowPassMore to Average7x7 to HighPassMore and then pressed the OK to apply using PixelRestrictions for the galaxy only" and this is the result .x
