Complete package including 125mm diameter rings and 80mm guide tube.

Compatible with the CELESTRON NEXGUIDE guiding camera or any other model such as ZWO or QHY. Includes an extension tube to help achieve focus without having to use the diagonal. An extension tube with M42 thread (T-thread) helps to insert the barrel of the guide camera into the extension tube of the guide telescope. The extension tube serves as a 1.25" eyepiece holder and since it is T-threaded, only a T-ring is required to attach a DSLR camera.

Metal focuser with tension screws to minimize gear play so that it is easier to keep the guide star on the chip.
