The Sun in H-alpha light

A Solarmax II 60 BF15 H-alpha scope fitted with an IR/UV cut filter and an SVBONY SC705C OSC camera was mounted on a Skywatcher Solar Quest solar finding and tracking mount.  Using AstroDMx Capture, a 2000 frame RAW SER file was captured of the whole solar disk. The best 60% of the frames in the SER file were debayered and stacked in Autostakkert!4, wavelet sharpened in waveSharp and further processed in Gimp 3.
