Custom-Size Rings for Guide Scopes on Vixen-style Dovetail Rails

Custom-size rings for guide scopes on Vixen-style dovetail rails

(use the arrows on the left and right sides in the middle of the frame to scroll through pictures)

The rings are designed for mounting guide scopes on long Vixen-style dovetail rails provided on the top side of various telescopes, mostly RC and SC telescopes.

The design of the rings allows detaching of the rings from the rail without sliding them all the way off the rail: you can just take the guide scope off the rail if the adjustment screws are loosen further away

The rings will be made according to your specification. Please provide the required diameter of the tube for which you need the rings in the field below.


  • 3D-printed parts
  • two adjustment screws
  • screws and nuts for the assembly

Please note that this product is shipped as a kit for assembly by the customer.
