AR12715 in the Ca II K line. C11 280mm telescope.

Post by Valery »

Hi all,

Here is the image from my large archive of our sun images. A fairly active AR12715 group as it was early morning of June 21 2018.
I imaged it with my C11 280mm SCT equipped with the ARIES 295mm two bands DERF filter and PST CaK etalon. Camera was
Balser 1920-155. Seeing was average with some improvements. This image was taken during one of such improvements.

Hope you like it. And this was less than half of year ago!
