Description

Time-lapse animation created from 77 recordings between 15:25 and 15:50UT on April 18th 2023. Each recording was 15 seconds long with a framerate of 60 (900 frames) and 5 seconds delay between each recording.

The recordings where obtained using a Coronado 90mm frontfilter mounted on a FLO StellaMira 80mm ED f/10, BF15 w/Baader 35nm H-Alpha and Beloptik ITF and Player One Mars-M camera mounted on a ZWO-AM5 mount guided with Hinode SolarGuider.

The 100 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 12fps effectively compressing the 25 minutes of duration down to just 6 seconds.
