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 each time out of 1000 recorded frames one frame has been constructed 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.
