Description

Timelapse animation created from 160 recordings between 15:08 and 15:48UT on August 2nd 2024. Each recording was 14 seconds long with a framerate of 135fps (1890 frames) and 1 seconds delay between each recording.

The recordings where obtained using a using a  TS-Optics ED 102mm f/11, with an Altair Astro 115mm TRIBAND H-Alpha D-ERF, Lunt CaK 1200 module, Baader Q-Barlow 2.25x / 1.3x (working at 2.25x) and Player One Mars-M camera mounted on a ZWO AM5 and guided with Hinode SolarGuider.

The best 400 frames from each recording was stacked in AutoStakkert!4 before they were aligned and sharpened in ImPPG. The images was then contrast-stretched in Adobe PhotoShop before deflickering in GBDeflicker. Timestamp annotation was added using IrfanView and the final animation which was created using PIPP at 15fps. This effectively compressed the 40 minutes of duration down to just 10 seconds.
