About this image

This GIF represents a time-lapse image of the prom on the South West limb of our Sun on 21 April 2022.

The time-lapse is made up of 107 video files spanning 500 frames each at c40fps. Each video file is separated by 30 seconds. Imaging commenced at 08:58:34 UT and finished at 10:15:25 UT.

I then took each individual video file and stacked this in AutoStakkert3! to construct 107 individual images representing 25% of the best 500 frames.

These 107 images were then processed in PixInsight, aligned in ImPPG and a GIF created in PIPP.

Excellent work John. A lot of work to produce that, but interesting to see changes over such an extended period. Well done.
