Hello,
Here are the results of my observing session of May 28 2018.
Unfortnately, the seeing was mediocre at best, especially in the CaK.
Images were obtained in CaK, then in 655nm continuum (unheated etalon) and then in H-a core.
Very different appearance of the Sun. It is a shame that the best seeing was when I imaged it with unheated etalon!
Once the etalon has reached it's temperature, the seeing told me bye bye and soon I quit the session.
Telescope used: C11 280mm F/10 SCT equipped with the ARIES 295mm DERF.
Thanks for looking and comments.

Re: The Sun in three different WL C11 scope.
These are a great comparison Valery I tried an unheated Quark once and couldn't see anything but a blurred blank disc, you are lucky to see some contrast and find the granulation. I struggled to get any contrast even on band.
