AR12671 in H-a and CaK through C11 + ARIES DERF

Post by Valery » Sun Dec 24, 2017 8:06 pm

Hi all,

These cloudy days I reviewed my images of the sun in H-a and CaK taken earlier this year with
my C11 telescope equipped with a new two bands (H-a and both Ca II K and H) filter.

Here are two images taken in Ha (August 19) and in CaK one day later (August 20).

Seeing was good August 19 and somewhat less stable August 20.


Thanks for looking and comments.
