Almost a year ago, I filmed a very beautiful prominence, but all hands did not reach properly to process it.
-Celestron 102\660+Coronado PST H-alpha
-mount Celestron NexStar SE
-ZWO IR-cut filter
-camera ZWO 224 MC.
Processing: Autostakkert (42 movies per 250\500 frames).
Duration: 11 minutes.
Location: Russia, Anapa, backyard.
The prominence is about 15 times the size of Earth. According to my estimates, in 15 seconds the prominence moved to a distance of the Earth’s radius, that is, about 6000 km. The speed is 400 km / s and more.
