C8 & Celestron Advanced GT C8 & Celestron Advanced GT The Celestron 8 (C8) is our smallest Schmidt Cassegrain telescope not accounting for binoculars or finderscopes. The telescope is usually attached to a Celestron Advanced GT mount, which can be can be set up by a single person because of its compact construction.

This disk is used to stabilize the legs of the tripod from the inside. The rod that punctures this disk will be screwed (with the side showing the thread) from below into the basis of the...

The tube is equipped with a so-called dove tail (the orange thing) that allows a quick and easy attachment of the tube to the mount.

Thread the screws on the side of the sun filter, so that it cannot fall off when the telescope is moving. Before using the telescope you have to tare the rotation axes.
