The Sun in H-alpha light

First light For the Altair 462M2 mono camera fitted with an UV/IR cut filter, with the Solarmax II 60 BF15 H-alpha scope mounted on a Skywatcher Solar Quest solar finding and tracking mount. Not ideal conditions with lots of clouds interfering. Two sets of 1000 frames were captured in 16 bit with AstroDMx Capture. The best 50% of frames in each set stacked in Autostakkert!4, stitched in MS ICE, wavelet processed in waveSharp and further processed in the Gimp 2.10.
