The guide tube (Guidescope) is mounted parallel to the actual tube - ideally with guide tube clamps, in which the guide tube can be easily moved. At the camera end, a camera can then be connected with which the tracking control of the mount is automatically performed. Thus, long-time exposed images of the night sky are possible.
Cameras, which are useful for guiding, have a 1.25 "socket, which can be easily inserted into the guide tube.
This Guidescope has a large field of view of 5.7 ° and the RotoLock clamp by William Optics. Thanks to this clamping, the connection to the guiding camera is fixed and centered.
