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

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
