I went to the River Ridge Observatory with an admittedly ambitious agenda for the evening, three rigs, nine objects. Two rigs involved telescopes, the third a DSLR with wide-ish angle lens on a simple stationary tripod pointed north in hopes of aurorae. The aurorae did not disappoint. They started about an hour after sunset and went on like this for another hour. Even after they dimmed, they continued for much of the evening. The video here is made of 197 15 second frames at two frames per second.

Until now, I’ve concentrated on combining images to highlight the corona or show a progression of the phases of the eclipse. I knew I had at least one image that showed the very prominent prominence (pun intended). That prominence was clearly visible to the unaided eye. Click to zoom in.
