The Moon - 2022-04-16-05:05 UTC - Crater Tycho_Southern Lunar Hemisphere

This image is a testament to what is possible with the tools available to today's amateur astronomer. During the capture session, transparency varied between below average and poor, and seeing had similar variances. The data is so bad that some of the pieces of this 20 panel mosaic had to be manually pasted and nudged into place, because photomerge could not line up the panels. Also, the changing transparency meant that the amount of the light reaching the sensor for each frame varied. I compensated for this as best I could by adjusting the brightness, but it seems that other values probably needed to be adjusted as well.
