The video shows a gigantic Solar Prominence several times larger than Earth. The elasped time is around 2 hours for the video. I shot this video with my Coronado 90mm filter and Tak130.
@Zvezdo4et1982 - This is an original Coronado 90mm Solar Max filter with a BF15. There are some cheaper H-alpha telescopes made by Lunt Solarsystems you might want to look into.
Wow!!! Is <0.5 or <0.7A? I want to buy Coronado SolarMax II 90 <0.5A BF 30, but in Russia the price $ 15000:(
