Description

The time-lapse animation is created from 211 recordings between 06:19 and 07:30UT on May 14th 2023. Each recording was 15 seconds long with a framerate of 100 (1500 frames) and 5 seconds delay between each recording. 

The recordings where obtained using a FLO StellaMira 80mm ED f/10, Lunt CaK 1200 module, Baader Q-Barlow 1.3x and Player One Mars-M camera mounted on a SkyWatcher SolarQuest Alt-Az mount guided with Hinode SolarGuider.

The 100 best frames from each recording was stacked in AutoStakkert!3 before they were aligned, sharpened and contrast stretched in ImPPG. 

The frames was then cropped and the animation was created in PIPP at 15fps effectively compressing the 1 hour 11 minutes of duration down to just 14 seconds.
