Hi all,
He is the image from my 2017y. archive.
August 21, 2017. The Sun was very active and I took some photos in Ca-K.
C-11 280mm F/10 SCT was used with ARIES full size front mounted DERF and
CaK PST etalon.
Seeing was average with some improvements.
Thanks for looking.
Valery

A very impressive image, Valery. August 21 was the day of the eclipse in the US, right ?
