FIRESTORM ON THE SUN ! Taken by Sylvain Weiller on May 9, 2017 @ Jerusalem, Israel

As soon as visible this morning it was a huge, looking quiet, prominence !

5 hours of imaging using FireCapture give a radically different feeling ! 45s acquisition (with SSM to reject bad seeing frames during this time) every 3 min (135s wait). FL-102S + Coronado SM90 + BF30 + ASI174MM.

Processing AS!3 then RegiStax5 then StarMax (for squaring the images as prominence was faint) + VirtualDub + PIPP for GIF lossy conversion ...

Better quality (lossless about 25 MB) will appear later on my site http://sweiller.free.fr
