Half hour of lightning is "compressed" into ~20s, each subframe is 8-12s long and played back at 30fps. My Cosmicar 8.5mm is out of focus, need to adjust it. Not exact astronomical, so it's more like a equipment testing.
Taken by my DBK 21AF04.AS mostly with Cosmicar 8.5mm, part of the video is taken with Fujinon 25mm, both at around f/12.
