Hello my friends,
I was lucky enough to capture the image of this very large AR during the flare M4.7 on May-9th. I also did a movie capturing the event from the beginning to the end. The link of the movie in Youtube is below, and the image was taken right in the climax of the emission.
My solar setup is:
For Ha: 0.4A Daystar ION filter connected to a 127 f7.5 Scientific Explore APO refractor via a TeleVue x4 PowerMate. The camera is a DMK41 mono.
