Sun FD in H-Alpha 20th of March 2022 - 3 hour timelapse

Post by arnedanielsen »

Dear friends,

I've finally managed to process the timelapse sequence from March 20th. The disc was rather quiet, but it's nice to be able to practice recording and processing skills.

The timelapse animation is made from 540 recordings each consisting 240 frames (20 seconds at forced framerate of 12fps). The best 40% from each recording was then stacked in AutoStakkert!3, aligned, sharpened, and contrast-stretched in ImPPG before deflickered in GBDeflicker. The final processing step was downsizing to 50% and creating the resulting animation in PIPP at 15 fps effectively compressing the 3h 0m down to 36 seconds.

FD image in H-Alpha using a Coronado 60mm/BF15 w/Beloptik ITF, stopped down to 50mm, Baader 35nm H-Alpha and ASI 178mm mounted on a SkyWatcher AZ-GTI in EQ-mode.

Nice animation Arne! You can actually see the rotation of the sun and I see those active surge proms on the Western Limb. I haven't done a full disk animation in a long time, I may just have to try another one soon.
