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.

You have been getting some absolutely superb full discs this year Ivan :bow :hamster: :bow

This is amazing work Ivan, what camera and exposure settings are you using for triple stack imaging?


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.

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.

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.
