First build of the second version of the setup based on a homemade accordion.

First assembly of the second version of the setup based on a homemade harmonic drive. This time it's an all-in-one version. I hung the box with the electronics and the battery as a counterweight. During the second assembly, I converted the focuser to a belt drive and replaced the heater with a 4.5W 12V heating cable. The purchased heater was glitchy — either the heater or the camera would act up. All that's left is to attach a heat pump to transfer heat from the sensor to the lens.
