152mm A+M Refractor(OfficinaStellare-1200F/L) using a TeleVue 2XPowerMate with a 35mm T-Ring with step-rings and a DeepSky Lumicon 2in. filter , and , a CanonEOSII RebelT7i modified UV-IR @ Hutech . This image as MaximDL Pro V6.16 RAWMonochrome Autosaves images is one 367secISO6400 and one 427secISO4600 and one 487secISO6400 with the RebelT7i's 'in-camera' 'Long Exposure Noise Reduction ON' as a MaximDL Pro V6.16 RAWMonochrome Autosaves with a 67secISO100Flush-frame before each 'light' frame at ISO6400 . I Sum stacked the images and worked on it as good as I could get it . The 'object' is large at 2400mmFL and daylight was approaching . This 'object' might work with more images in the stack . With the DSLR's 'LongExposureNoiseReductionON' it's clear to see the edge 'blurs' aren't there , but at four minutes there would be without 'noise reduction' .x NotePad update about "ImagesPlus" in the JPG 'lower section ; And a RAWMonochrome Autosave Sequence for a DSLR in MaximDL Pro .x
