Hi solar imagers
On a totally blank sun face the CaK and CaH offer more to see, especially at a high resolution.
Here is a recent image of the sun (near the center of the disk) I took in CaK line at a high resolution.
The angular resoluton at CaK line 393nm is 1.67x higher than at H-a 656nm. So, my C11 280mm telescope
has the same resolution as a 468mm telescope in H-a line.
I was lucky to take several images where a full resolution has been achieved. This image is one of them.
Right click on the image and choose "open in a separate window" to see the image at a full resolution.
Thanks for looking.
Valery.

Very impressive Valery, the details are very sharp and remarkably angular

That's excellent Valery! Very much like DOT images. You are at the cutting edge of hi-res solar!

Dear Valery,
That is superb CAK imaging. Congrats!!! What is your imaging train like? (e.g. from the output of the SCT to the camera).
