Well I last tried this some 4 years ago (see
https://www.astrobin.com/128750/C/), but clearly haven't learned my lessons....!! My October 2014 attempt was full of huge holes despite using a scope/camera combination (10" Meade SCT + DBK21AU.04 colour camera) that gave a significantly larger FOV per frame than my current rig and used a mere ~70 videos, so what was I thinking trying again with the smaller FOV of my C14 + ASI120MM-s...!!
I took great care (well I tried to anyway) to allow margin overlaps as I move systematically across the lunar surface in zig zag vertical passes, shooting some 121 videos over an elapsed time of 2.75 hours. I started shooting videos of 2000 frames each, but halfway through realised that I would run out of disc space on my laptop so reduced capture to 1000 frames per video, even then capturing in excess of 160Gb data. All videos were shot using an Astronomik Green filter.
Each video was processed in autostakkert (AS3!) selecting best 200 frames, then sharpened with wavelets in Registax before taking into PS for final tweaks and cropping out edge artefacts. The individual frames were stitched together one by one in iMerge to produce the final high resolution image......
