Hello,
Given the newly formed sunspots, I scheduled a really quick imaging session (no time for H-alpha).
Very calm atmosphere but transparency wasn't exceptional.
During the last Zoom meeting I took notes and this time I tried to apply some of the acquisition advices discussed.

Hello,
Finished processing another set of close-up in WL, obtained with a 5X barlow
That was a bit of a stretch, since they didn't end up very crisp.
