H-alpha solar images June 7th with AstroDMx Capture for Linux

A Solarmax II 60 BF15 H-alpha scope was mounted on a Celestron AVX mount. A DMK 21AU04.AS camera was placed at the prime focus and 4 overlapping sectors were captured as 2500-frame SER files to cover the whole disk, using AstroDMx Capture for Linux running Voyager Linux.

Also, a lens from a x 2 Barlow was screwed onto the front of the camera nosepiece and two overlapping regions covering AR2765 and a nearby filament were captured as 2500-frame SER files.

The best 10% of the frames in the SER files were stacked in Autostakkert 3.10, wavelet processed in Registax 6, stitched with Microsoft ICE and post processed in the Gimp 2.10.
