Hi all,
Nov 2, was a clear warm day. Seeing was variable from barely
acceptable to good.
I decided to image the sun in Ca II K and H-a.
Telescope is my trusty Celestron 11 280mm F/10 SC equipped with the ARIES
295mm DERF two bands filter and PRG Flea 3 b/w camera.
The Ca K filter is a Double Stacked resulting about 1,5A bandwidth with a very steep transmission curve.
H-a filter is a single stacked.
Thanks for looking.
Valery.

Hi Valery,
As usual great captures, despite the seeing.

Good results given the conditions Valery, you can tell the seeing is not as good as you normally get.

Hi Valery...
These are very good images...even with the variable conditions your capture and processing turned out very well.
