    CanonEOSII RebelT7i'modi.UV-IR @ Hutech' thru a BaaderUV-IR Cut-Off 2in. and OrionPolarizing 2in. filters thru a TeleVue .8XReducer/Flattener for 950mmF/L thru a 152mm A+M Refractor(OfficinaStellare) on an Astro-Physics 1200GTO '2010' Mount . Eighteen CR2.s were 'Deinterlace' in MaximDL Pro V6.20 and 'bilinear' SigmaClip stacked . Various exposures and ISO's were used : four 35secISO25600 , six 60secISO12800 , four 90secISO6400 , two 118secISO3200 , and two 178secISO1600 total CR2.s were 'deinterlace' to 'Odd' and 'Even' images and stacked again together to try to fix 'streaks' in the images ... if possible ... here is the resulting jpg with only 'screen-stretch' and 'Color-Balance' applied and the same settings to both jpg images .x
    This was an experiment to see if it helps short exposure images to look better , Sigma-Clip was used on one
    version and Sum on the other . I had these 'one-shotColor' images so I tried to see if they can look better .
    A single image of these is real scratchy looking .
