    Here is a wide view of Andromeda Galaxy with my (not modded) Canon T6i with Mark I, EF lens 100mm to 400mm on Orion Sirius Pro mount managed by EQMOD / PHD 2.6.5. My wide image is set to 400mm, resolution managed by Backyard EOS with image view scale of 1.95985 then multiply APS-C scale @ 1.6 = 1.22490625 final image scale.

    Formula to determine image scale.
    Scale = Camera pixel size in (Microns) * 206.3/ focal length * (APS-C 1.6).

    1.22490625 = 3.8 * 206.3/400mm *(APS-C 1.6)

    Some weeks ago, I imaged the inner core of Andromeda using Canon T6i with Celestron 8SE at 2178 focal length, 8SE is just amazing.

    I started at 0000 hours but, due to rainy weather my window was shorted to 1.1 hours of exposure time at 22 x 180 seconds at ISO 1600, light pollution filter I'm using, IDAS LPS D1. Come to post processing, it was a bit of a challenge for me, in my view of Andromeda, I tried to preserve the luminance, the halo front of the darkness in the ocean of stars. By 2nd week I was able get another 2 hours of clear skies with half-moon to the south, I did better in post processing.. Yeah, my attempts finally came to fruition.
