About this image

Created this animation by first off using Firecapture sequencer to capture 30 SER files of 800 frames each with a delay of sixty seconds in between each recording. Selecting files that were not affected by passing clouds (reduced to 16 SER's in total) stacking was then carried out in Autostakkert. Processed in Astrosurface then aligned in IMPPG. GIF was built in GIMP.

First SER was recorded at 13:27 UT and the last SER at 14:14 UT.
