    1st image: CanonEOSII RebelT7i modified UV-IR @ Hutech , using a Canon 75-300mmLens at 300mmFL with a Baader 7nm HydrogenAlpha 2in. filter . These images were at night while the Moon was rising , but , the clouds were accumulating so there was less light as this experiment went on . This image was after a 67secISO100Flush-frame and then a 427secISO6400 'light' frame which is this one . There is a glow haze at the edges because there wasn't any 'noise-reduction' . x

    2nd image: CanonEOSII RebelT7i modified UV-IR @ Hutech , using a Canon 75-300mmLens at 300mmFL with a Baader 7nm HydrogenAlpha 2in. filter . These images were at night while the Moon was rising , but , the clouds were accumulating so there was less light as this experiment went on . This image was after a 'SimpleAuto-dark' and 67secISO100Flush-frame and then a 'SimpleAuto-dark' and 427secISO6400 'light' frame which is this one . There isn't a glow haze at the edges because there was 'noise-reduction' . x

    But , due to the changing night sky all images with 'SimpleAuto-dark' had color differences ... like 'blue' tinted but can be fixed with "Levels" for 'Blue' gamma reduction in MaximDL Pro . .x
