152mm A+M Refractor(OfficinaStellare-1200mmF/L) using a TeleVue 2XPowerMate for an effective 2400mmFL with a CanonEOSII RebelT7i 'modified UV -IR @ Hutech' on the 2XPowerMate with a 35mm T-Ring and the BreakThrough filter in front of the PowerMate . Also , using an Astro-Physics 1200GTO '2010' Mount at 1xSiderealGuideRate . I did 40-RAWMonochrome Autosave images thru MaximDL Pro V6.20 as 30sec. exposures for four each of ISO800 and ISO1600 , and eight images each of ISO3200 and ISO6400 , and about eight each of ISO12800 and ISO25600 . It was hard to remove the Average stacked ISO800 and ISO1600 FITS's 'banding' in the 'background' but I 'screen-stretched' with the 'red' carot to darken the image so there wasn't any 'banding' and then I used the "Stretch" command and I made the FITS a 16BIT image and then I use the "Remove Pedestal" command and I used ' 25 ' to pull the data away from the left edge for some room and I made it a 16BIT image again and then 'Save As...' IEEEFloat . I Average stacked each ISO type separately in their own Folder and after that I Sum stacked all the FITS ISO images . Then I did other commands and this is the result for the NGC5982 using only 30 second exposures .x
