h-alpha and CaK, February 26th, 2021

Post by LTHB »

Quite nice spring weather on Friday, so I could follow how the active groups develop. I started with CaK, and by the time I had the h-alpha scope out, the seeing had deteriorated a bit.

First a disk in h-alpha for overview (I forgot to shoot a disk in CaK...) and then a closer look at the active regions in both wavelengths:

Finally the big prom in h-alpha and in CaK:

Kind regards,

Frank
