The hight was calutated from the flight time (125.4 minutes) and the accent speed (4.5m/s) The accent speed can be calulated from the amount of free lift there is.
I didn't other instruments on board besides the cameras and tracker, my main aim was to capture images of black space.

The size of the balloon is based on the manufactures specs at that hight.

Glad you like the video, I know nothing about video editing so it's a bit of a new thing for me.
