I have been testing the Kessler Crane Shuttle Pod dolly system for the past few months. Really great piece of gear.
If you already own a newer version of the Kessler Crane, you already have the track!
I explain what the Shuttle Pod is, how to set it up and how to use the Oracle controller and ElektraDRIVE motors.
Check out a multi-layer scene where I clone myself in a motorized dolly move and, later in the video, watch some epic motion astro-timelapses.
