Details:
A DMK camera was used with a Solarmax ll 60 BF15 H-alpha scope and a CaK PST Ca K-line scope to image the Sun. In each case, AVIs were captured in 4 overlapping quadrants of the solar disk. The AVIs were stacked in Registax 5 and the resulting images merged in Photoshop. A region with two large prominences was imaged twice, once exposed for the disk and a second time exposed for the prominences. The two images were combined in Photoshop.
