Managed to capture some H-alpha shots of the sun just after lunch. Some lovely detail visible in the big ARs which are predominantly in the western hemisphere. Right near the eastern limb, a pair of small, very bright spots were visible. I gather that two X-class flares went off in that area around that time, so I either caught the aftermath, or the start. I stacked the images with AS!2 (using flats created with Registax and ImageJ), did wavelet processing in Registax, made the mosaic in Autostitch64, sharpened the result with Fitswork4 using deconvolution, and used curves for pseudocolour with Gimp. Full resolution here. Without pseudocolour: Full resolution here. Without deconvolution Full resolution here. Pretty chuffed with this result, especially with the 35mm aperture of the LS35. I used the TV PowerMate 2.5x and DMK21 with Firecapture. Deconvolution really adds extra sharpness.
