March 31, 2020: Spotted the spot

[michael.h.f.wilkinson]

Managed to take the APM 80mm out into the garden for a little sun-spotting. Grabbed 1000 WL frames and 2000 Ca-K both with the ASI178MM. Stacked 250 of the best in AS!3, sharpened using ImPPG, and postprocessing in GIMP.

Some hints of proms, but I didn't have time to fire up the H-alpha kit. But, hey, we have a spot!

Great to see your Solar image sets again Michael, especially the Ca-K images.
