Additional information requested:
the magnitude of Yaogans is about 5, barely visible to the naked eye (but sometimes they flare, as you can see in the beginning of the movie). The source is Calsky as usual, I used the star chart calculated from different locations and I took my car (about 1h driving) to go the precise location from where they crossed the deep-sky objects.
This time, tracking is just manual with a photo tripod and fluid video head.
