Description

Time-lapse animation created from 175 recordings starting 13:59UT on May 17th 2022. Each recording was 20 seconds long with a forced framerate of 65fps (1300 frames) and a 10 seconds delay between each recording. The recordings where made using an ASI ZWO 174MM together with a DayStar Quark Chromosphere through an Explore Scientific 152AR. This setup gave a focallength of 4250mm and a sampling of 0.28" per pixel. 

The telescope was mounted on an SkyWatcher AZ EQ6 Pro in EQ-mode and guided with a Hinode SolarGuider. 

The best (sharpest) 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 12 fps effectively compressing the 87,5 minutes of duration down to 14 seconds.
