    This is probably the best shot I got from the annular eclipse on Oct. 14th, 2023. As the Moon crosses the edge of the solar disk, the "roughness" of the lunar mountains cuts the solar disk into pieces occluding it unevenly. This is probably the coolest astrophotography shot I've taken.

    • Telescope: Meade ETX125 127mm Mak f/15
    • Mount: Sky-Watcher HEQ5
    • Focal length: 1900mm
    • Camera: ZWO ASI585MC
    • Filter: Baader Solar Film 5.0, Optolong Oiii 6.5nm 1.25"
    • Gain: 400
    • Binning: 2x2
    • Exposure/frame: 1.4 ms
    • FPS: 46.9
    • Sub-frames: 1000
    • Software: Captured using ASI Studio. Autostakkert! to export AVI into 1,000 .tif frames. Siril to debayer the sequence. daVinci Resolve for final rendering.

    The atmospheric shimmering adds to the unreal feel to the video as well. This was a recorded video taken during the eclipse party we had in Albuquerque, New Mexico. This is basically the raw video played back in approximately real-time with little processing done. The sun is green because I'm using a 500nm filter to get as sharp an image as possible with my equipment.
