This is a 6-panel mosaic of the solar disk in white light with a 10nm bandpass filter centered on 540nm, and shows three
active regions including AR 12871, 12872, and 12873.
It was 90°F out when I captured this between 1:24 and 1:40 PM UTC-7 on September 21, 2021. I wrapped my gear with sheets of packing foam to help shield it from the heat. There was some high loft smoke from forest fires east of my location. Seeing was a bit rough, but I think I still got some good data.
Each panel consists of the best 10% of 2min worth of captured data, or about 500 frames per panel. Wavelets were applied to each panel with RegiStax. The mosaic was then stitched together by hand in Photoshop.
