This video is composed of 16 photos taken in 20 minute intervalls over more than 5 hours from 19:00 to 00:20.
For each photo 1000 frames have been aquired with a ZWO ASI290MC at 4 ms exposure, 200 gain, 140 fps and
post processed with AutoStakkert and RegiStax. So everytime from 1000 frames one frame has been extracted for
the final video by stacking and sharpening.
I also had to align the processed images as I used an atmospheric dispersion corrector, wich was kept fixed in position during the night.
