These are my first image(s) with my QHY247C OSC. I think it turned out okay relative to the mono image which was the first one I did with the QHY163 (http://ram.org/images/space/scope/1.4.1.5/norm_m31_Stack_32bits_360frames_5400s.v6.jpg). You can see the evolution of my gear and technique since the last two years. The mono image was taken on July 15, 2017 which was purely Sharpcap based livestacking, no dark subtraction, etc. on a Celestron AVX mount. Now the OSC image is a bit longer (though the 360 frame one looks good and I processed it a bit differently which I also include here) and the mount is a Paramount MyT and the processing is all done using PixInsight.
I processed a total of 720 15 second frames (3 hours total exposure) in PixInsight stacked the best 600 or 360 frames to produce these images using SubframeSelector. Inline version of the 360 frame version (processed a bit differently) is below and full sized image of the 90m version (360x15s) is here: http://ram.org/images/space/scope/1.7.4.6//m31_c_360x15s_90m.jpg
Description: This is an image processed differently using only the best 360 of the 720 frames I collected using SubframeSelector in PI.
