Pictures attached.

141210: Second axis geartrain (basically a curved screw barn door)
140902: First axis stepper
140852: Lower circuit board. This connects to the battery, has a PCA9635 that the Pi sends I2C to, and has MOSFETs that drive the steppers. It also connects power and I2C to the upper circuit board through a slip ring.
140828: Front of the eq platform
140743: Side view of the whole thing (minus the Pi and upper circuit board because I haven't finished those yet)
140703: Scope and guide scope
140649: Focus servo
