The hydrogen alpha is superb as always and the CaH is your best result yet. In my opinion, the infrared Ca lacks contrast in that the chromospheric network is poorly visible. I don’t think this is due to any inherent difference in UV vs IR calcium chromospheres but points to a lack of contrast and s...
