Mount and other components

Mount:

The design for the mount is a simple Dobsonian. It is easy to construct and the easiest to use.

There are main part of a dobsonian mount are:

  • Wooden side supports
  • Bearing/D support for OTA
  • Castors/Ball bearings for azimuth rotation

I will let the pictures do the talking as the mount design is pretty straightforward:

I made several components to automate the mount. These included motor brackets, OTA supports and the motor-gear engaging mechanism.
