Negative night cloud observation. The conditions were good, and the horizon of the observation site was completely unobstructed, however, no trace of the night clouds was visible during my observation. In this still demo, two images, both taken in a northerly direction.

Picture 1 at 1:24

Picture 2 at 1:55
