I was wondering if you can spot polar faculae in your CaK images? The BAA at the moment is trying to get data this year on polar faculae (solar minimum) however not many of us take white light images. Do you think they would be able to use our CaK images instead?
Maybe? not sure?

Put the reducer closer to the chip. You're just photographing the vignetting,

Re: Beloptik ha system

Personally, no. Lots of people on here have tried the telecentric / air spaced etalon route and it yields results with too wide a bandpass.

Re: Sol from the 13th of February 2019.

Mighty fine full disks. Slow cameras are fine at this scale.
