There were a lot of photographers and videographers capturing the moment of totality for the Great American Eclipse last month, but JunHo Oh was able to capture some incredible footage of the moment of totality in real-time.
JunHo Oh used a 2160 f/12 telescope with a Panasonic Gx85, and a RST-150H robotic mount from Rainbow Astro, which traced the edge of the totality while it occurred. He took the footage in Warm Springs, Oregon.
“RST-150H weighs only 3.5kg (7.7 lbs) but carries up to 15kg (33 lbs) of optical equipment without any counter weight,” Rainbow Astro writes of the mount. “RST-150H mount is specially programmed to trace Sun’s peripheral during total eclipse period to match C2 and C3 contact moments ... This allows us to catch breath stopping moments of the Sun set and rise over the Moon’s horizon.”
In JunHo Oh’s video, you are able to see the eclipse reach totality before tracing the corona.
