K.Crankshaw with his partners wanted to build something in Galileo’s memory who made important discoveries in astronomy. They though that the easiest way to learn sky objects is when someone or something points them. So they came up with Arduino based accurate laser pointer which can points its beam directly to wanted objects. Sounds cool.
They build built a wooden pan and tilt stepper motor driven mechanism which can point laser to any direction on a top half of sphere of sky. Arduino communicates to python code via serial interface to get desired sky object location then it drives motors to point its position with laser. Why not to scale it up to work with telescope?
