    Early days. This was an experimental rig made from mostly inexpensive parts. I later decided core type motors didn't make good servos and rather than spend the money on coreless swiss ones I switched to open loop and steppers. The pentax lens has an arduio cam behind it mounted to some drain pipes with a hand carved bayonet for the lens. The small sensor size really limited what lenses I could use though and I scrapped the project. That and the ps2 cam under it was an early attempt at autoguiding. The motor lope proved to be too much for the system.
