Re: triple stack mosaic from May 20th
Thanks a lot, Petr, I appreciate your opinion. I often watch your close-ups, and I also want to start making them, but I don't dare.

Re: triple stack mosaic from May 20th
You have been getting some absolutely superb full discs this year Ivan
Can you remind me what size the triple stack is?

Re: triple stack mosaic from May 20th
This is amazing work Ivan, what camera and exposure settings are you using for triple stack imaging?
Martin
Martin
Skywatcher 120mm F8.3 open frame refractor, 2" Antlia dual band ERF filter as a sub energy rejection filter, Flip Mirror to either a Baader TZ4 telecentric focal extender, Combo Quark Chromosphere, Naked PST etalon for double stacking, ASI74mm camera, or an Antlia 5a Cak filter, ASI290mm camera. 100mm aperture is stopped down to 50mm for Cak.

Re: triple stack mosaic from May 20th
Thanks a lot, Stuart! Your FDs are great!
Ivan
Thanks a lot, Mark!
Ivan
Thank you very much, my friend!
Ivan
Thank you very much, Alexandra!
I try to improve my skills and setup. I use an external etalon 50mm and two internal etalons Lunt50 https://flic.kr/p/2pP1xGb

Thank you very much, Valery, your close-ups are wonderful, Quark shows very well.

Thank you very much! I usually make 12 to 15 fragments to be 100% sure that all areas are covered. But, theoretically, I can do without 9.
Ivan
Thanks a lot to Maurits!
Ivan
Thanks a lot Martin! Every time I change the settings, it depends on seeing, the presence of flares, the height of the Sun, clouds. I don't get attached to the histogram, but try to evaluate the picture to my taste. Specifically, these fragments were shot by Shutter=10.25ms
Gain=100 (18%). But I can increase the exposure (although I do it very rarely) to 20 ms. At the same time, the picture will not lose sharpness, because the scale is not very large.
