The 80mm Guidescope Package from Celestron is a complete package containing two 125millimeter rings along with the guidescope. This scope is compatible with Celestron's NexGuide Autoguider. It includes an extension tube to assist in reaching focus without a diagonal. An M42 thread on the extension tube allows an easy sliding of the NexGuide autoguider barrel into the extension tube. There is a tension screw on the focuser to minimize the "play" when focusing.
