After a night or two of fits and starts using SGPro's mosaic and plate solve for the first time, I netted 8 hours or so of pretty good data over 4+ hours in two nights using a side-by-side simultaneous imaging setup designed to match FOV's. The Mosaic was a 3 panel attempt for each camera/field of view.

FOV 1 was done using a Hutech modded Canon 6D in a Tak FSQ106 at prime (F5). FOV 2 with a saddle mounted, Baader Ha filtered (7nm) SXVR-H694 adapted to an EOS EF200 MM Canon zoom set to F5.6 and fit with my home-made circular-hole drilled lens cap to eliminate the iris spikes inherent at that F-stop. The Canon 70-200mm zoom is not the best of lenses for astrophotography (no zooms are), but the sensitivity of the 694 combined with the higher f-stop crisped up the Ha image enough to make for a reasonably pleasant HaRed+GB+HaLum processing attempt.

Mosaic integration and overall Processing was done with Pixinsight and finished in PS4. Presented as Ha-Red/Green/Blue + an Ha-Luminance layer with some color saturation and enhancements done in PS4.

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.
