Description

Time-lapse animation created from 110 recordings between 07:50 and 08:45UT on August 14th 2022. Each recording was 20 seconds long with a framerate of 135fps (2700 frames) and a 10 seconds delay between each recording. The recordings where made using a StellaMira 80mm f/10, Lunt Calcium K Module B1200 2" Straight-Through Tube, Coronado 2x 1.25" Cemax Barlow (working at 1.83x for a focal-length of 1465mm) and a Player One Mars-M camera. Everything was mounted on a Sky-Watcher SolarQuest AltAz mount.

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

The animation created in PIPP at 12fps effectively compressing the 55 minutes of duration down to just 9 seconds.

The field rotation caused by recording being made in AltAz mode.
