August 11, 2022: 15-pane, full-disk, H-alpha mosaic

Recommended Posts

After the usual Wl and Ca-K disks, I grabbed a series of 1000-frame SER files for a 15-pane, full disk H-alpha mosaic. Seeing was a bit up and down, which meant I re-shot a few before I was content. I stacked 25% of each in AS!3, sharpened in ImPPG, and stitched in MS-ICE. Final postprocessing in GIMP.
