Description

The time-lapse animation is created from 40 recordings between 07:01 and 07:12UT on September 2nd 2023. Each recording was 12 seconds long with a framerate of 136 (1630 frames) and 3 seconds delay between each recording. 

The recordings where obtained using a using an iStar Asteria TCR 204-12 R35, Baader Cool-Ceramic Safety Herschel Prism Photographic 2", Baader ND OD 0.9, Baader 1,25" Continuum 7,5nm, Coronado 2x Barlow (working at ~1.8x) and Player One Mars-M camera mounted on a ZWO AM5 and guided with Hinode SolarGuider.

The 200 frames from each recording was stacked in AutoStakkert!3 before they were aligned, sharpened and contrast stretched in ImPPG. 

The animation was created in PIPP at 12fps effectively compressing the 11 minutes of duration down to 3 seconds.
