Description

Time-lapse animation from 199 recordings each consisting of 400 frames (20 seconds at forced framerate of 20fps). The best 100 from each recording was then stacked in AutoStakkert!3, aligned, sharpened, normalized and contrast-stretched in ImPPG before deflickered in GBDeflicker and colorized in PhotoShop. The final processing step was downsizing to 50% and creating the resulting animation in PIPP at 15 fps effectively compressing the 1h 6m down to 13 seconds.
Solar telescope was mounted on an SkyWatcher AZ-GTI in EQ-mode and autoguided using FireCapture. There's a small amount of field-rotation due to poor polar alignment.
