• After several (failed) tries over the last 5-ish years, I was finally able to capture an ISS solar transit!

    Took several hours of setup, as I had to move the rig out of my observatory to a suitable viewing location on the north side, due to the Sun's low altitude at transit time.

    • Equipment
      • Lunt LS50THa solar telescope, w/ B600 blocking filter
      • ZWO ASI178MM camera
      • Astro-Physics Mach 1 GTO mount
    • Conditions
      • Clear, 19°C
      • Sun altitude ~10°
    • Capture Details
      • 1536 x 1536 subframe, 6.5ms exposure time, ~ 18fps
      • 36 frames showing the ISS silhouette
    • Processing
      • Video created in Cyberlink PowerDirector 365
      • PD365 sharpening, exposure compensation, and brightness/contrast tweaks
      • 2 frames identified showing best detail of ISS, extracted from raw video, sharpened and histogram tweaked in PI, stills added to end of video.

    18°C is equivalent to 64°F, which is 291K.

    I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand

  • Very nice! Great work!

    Thank you, sir!
