A DMK 37AUX273 camera was mounted at the prime focus of a Solarmax ll, 60, BF15 H-alpha scope, mounted on an iOptron Cube Pro, AZ GOTO mount. AstroDMx Capture for Linux was used to capture two overlapping 1000 frame 8 bit SER files, which were Stacked in Autostakkert! 3.1, stitched in Microsoft ICE and wavelet processed in Registax 5.1, all running in Wine. The final image was post processed and colourised in the Gimp 2.10.
