Solar activity 05/11/15

These are 7-hour image sequence taken with Solarscope 50 and Olympus modified E-M5, guided by Hinode SG. We can see several flares.

50ssI’m still trying to figure out best possible configuration for myself by changing cameras and extending focal length, including teleconverter and flattener etc. I feel like simple prime focus (less number of lens elements) by 50mm F8 (400mm f.l) looks good compromise so far. Also Olympus’s tilt EVF is very convenient under the sun and allows to see the focusing difference more clearly than SONY’s EVF. I don’t know why. Epson-made EVF looks more suitable at least for solar imaging than SONY’s made.
