Hi, Chris:
A Telrad and base means: Telrad finder with its base (the base is stuck to the OTA). There are small plastic finger-screws which allow you to remove the Telrad from its base. By having bases on many scopes you can move the Telrad finder between scopes.
This link shows a Telrad base. It has adhesive which sticks the base permanently to the OTA.

Note that I am not offering a mount for sale. Only the OTA and the extras listed in the ad. You will need a mount in order to use this scope.
