Sun in H-Alpha on August 10 and 11. Most of the differences in the edge features (prominences) are because of different conditions at the time, as on 10th there were thin clouds covering the sun and on 11th there weren't. Also on one of the images I used a bigger magnification with the zoom eyepiece than on the other one. Can you spot which one?
Pictures were taken using a Coronado SolarMax II telescope and Canon EOS 500D camera with a Hyperion 8-24mm zoom eyepiece. For the Sun on the left: ISO 400, 1/80s, for the Sun on the right: ISO 200, 1/30s.
