Observations: Tested telescope and after alignment GOT works quite nice

Condition: Telescope is in good condition with minor scratches that will not impact functionality.  Optical system is in good condition and are collimated. Did not get a chance to verify GPS is working on mount.  This is a very heavy mount compared to most GOTO systems, but the dual fork should add stablility to the OTA.

 Comments: Bolts used to secure mount to tripod are not original but work fine.  Also Optical Tube Assembly (OTA) is not part of the original mount system, but works fine.  Updated Mount and control pad Firmware to latest version.
