CanonEOSII 6D 'stock-new 2017 model... from B+HPhoto' using an OrionSkyGlow 2in. filter thu two TeleVue 2XPowerMates for 4800mmF/L using a 152mm A+M Refractor(OfficinaStellare) on an Astro-Physics 1200GTO '2010' Mount on April 4 2019 after 04:00amEDT . One image is 11minISO4000 and the other is 8minISO4000 with light brightening early in the morning . I Sum stacked the two TIFFs and then put the result FITS into "ImagesPlus" and tried various commands because a strong 'green' cast was in the image and I had to try to reveal the 'blue' ; I did a Duplicate and applied a 'Stretch' for 'Hyperbolic' and then I 'blended' the original and duplicate together and did more commands . I was try ISO4000 to use as a normal 'broadband' ISO and it takes 11minISO4000 at this 4800mmF/L to get enough exposure . I will try the Lumicon DeepSky for more 'blue' and then the Baader UV-IR filter with an OrionPolarizer on the Trifid ... and try with a darker sky and for more images.. ...this image isn't cropped and shows the full content .x
