Hydrogen Alpha Solar Movies at 2000mm FL

The large diameter of the SM90 solar filter will support a  longer focal length, and results are great when seeing is good. TodayI felt seeing was good enough to use a Televue 2.5x Powermate, and with the tak focal length of 800mm, the flick was imaged at 2000mm. This hi mag  movie showing AR1166 reveals lots of rich detail in the active areas core.

The above clip was made from 1747-1918 UT, a few hours before the area let loose with an x-class flare. To improve the movie quality, I examined each frame for sharpness, and removed all mushy frames caused by atmospheric conditions. The movie below is a rework of a movie made several days ago. I realized after processing the movie that the settings in avistack2 were not properly set, resulting in a movie that lacked sharpness and appeared out of focus. i also removed the  mushy frames from the individual images used to make the movie I think the rework looks much better. A  2.5x powermate was used for this movie also
