A solar prominence in H-alpha light with a DMK 37AUX273 and AstroDMx Capture for Linux

A Solarmax ll, 60, BF15 H-alpha scope was mounted on a Celestron AVX mount. A DMK 37AUX273 camera was fitted with the lens from a 2x Barlow and was placed at the focus of the scope. AstroDMx Capture for Linux was used to capture a 10,000 frame SER file exposed for a prominence at 160 fps with a ROI of 640 x 480. A 3000 frame SER file was captured, exposed for the disk. Autostakkert! 3.1 running in Wine was used to stack the best 15% of the prominence frames and 50% of the disk frames. Registax 5.1, running in Wine was used to wavelet process the resulting images. The two images were combined and post processed in the Gimp 2.10.

Again, the DMK 37AUX273 proved its worth as a high speed capture device for H-alpha solar imaging with a ROI.
