Details:
A Solarmax ll, 60, BF15 H-alpha scope was mounted on an iOptron Cube Pro AZ mount. A DMK camera was placed at the prime focus. Two sets of 4 overlapping AVIs were captured so that in each case the whole Sun was covered. One set of AVIs was exposed for the disk and the second was exposed to reveal the prominences. The AVIs were stacked in Registax 5.1, merged into two individual images in Photoshop and then the two images were combined in Photoshop to produce the final image.
Also, a static tripod mounted Panasonic Lumix DMC-FZ72 bridge camera at 60x optical zoom, fitted with a Baader solar filter, was used to image the Sun. The camera was set to burst mode, ISO-100 and 1/1000s exposure at f/5.9. Images were captured in bursts of three. 90 images, precisely cropped and registered in Nicola Mackin's AstroCrop software were stacked and wavelet processed in Registax 5.
