The Sun today in H-alpha light. A 2500-frame SER file was captured by AstroDMx capture with real-time flatfield correction using a Coronado II 60 BF15 H-alpha scope and an Altair 678M camera. The best 50% of the frames in the SER file were stacked in Autostakkert!4, wavelet processed in waveSharp, and further processed in PixInsight, Photoshop CS2, Gimp and ACDSee.
