        • Huge solar prominence close-up time-lapse in h-alpha


          from Backyard Astronomy / Added

          The animation represent a close up portion of the sun of 8 February with the evolution of a huge prominence during an hour of observation. Images taken with a 100 ed refractor using a Daystar h-alpha filter at a focal of 2300mm, I reduced the focal a little to let it be whole inside the camera. When I saw this huge prominence I decided to make a time-lapse of its tiny movements; this ones was very slow and gave me the opportunity to take long exposures for each frame. I used 1 minute of capture for each frame, but after finishing the animations I'm wondering if it could be better reduce it a little to have a better composition of few faster inner movements. My intention was then to make few close-up animations of the more interesting formations but clouds arrived just after the first capture session. I will try few post-pocessing close-up, stay tuned.
