Assembly

Assembly of the TableTop is very easy. Carefully remove the protective packaging. Your TableTop arrives from the factory with the optical tube attached to the base – just install the visual accessories and you will be ready to start viewing with your new telescope! These accessories will be found in a box within the main box. Please save all original packaging. This will help protect your TableTop if you wish to transport it or in the unlikely event repair service is necessary.
