Details:
An Opticstar PL-130M CMOS camera was placed at the prime focus of a Solarmax ll 60, BF15, H-alpha scope. 2 x AVIs of 2000 frames were captured at maximum resolution of 1280 x 1024 pixels. One was exposed to show details of the disk and the other was exposed to show the prominences. The AVIs were stacked and wavelet processed in Registax 5 and the two resulting images were combined and colourised in Photoshop
