Hello,
During my livestream of the eclipse I have captured some beautiful h-alpha shots of our nearest star. Filaments, prominences, and faculae can be seen.
Scope: LUNT40 B600
Camera: ASI120MC
Imaging software: SharpCap 3.2
Processing software: GIMP 2.10 for sharpness and color contrast
Image 25102022_2: had a gain around 37 and exposure of about 11 ms. I kept adjusting them during the imaging.
Image 25102022_3 (yellowish sun): I pushed the gain to 100 to compensate for the clouds keeping the low exposure time as in the previous one.
No stacking, single frames.
