April 17, 2022: Easter sunshine in WL, Ca-K and my first full-disk 16 pane H-alpha mosaic in ages

Captured some solar data with the APM 80mm F/6, first with the Lunt Herschel wedge, wich revealed the huge active region that has just arrived.

Next I used the Lunt B1800s Ca-K module, to capture the inner chromosphere.

Part inverted, revealing some proms:

I then switched to the Solar Spectrum 0.3 Angstrom filter, Baader TZ-4 tele-centric, and Beloptik Tri-Band ERF for H-alpha. I captured 16 SER files, of 1000 frames each, stacked no less than 50% (stable seeing or what?) in AS!3, sharpened in ImPPG, and stitched in MS-ICE:

Loads of activity to be seen, lately

Gorgeous images. I have been following your solar processing tutorial sticky thread and it has been very helpful.
