These Celestron 125mm photoguide mounting rings are large enough to accommodate up to a 102 mm refractor guidescope. Each ring has a dovetail mount that clamps onto any optional Celestron CGE or Losmandy-style D-plate accessory mounting plate.
Alignment pins keep the ends of the clamps parallel when sliding onto a dovetail plate to avoid binding. The spring-loaded clamps also help prevent binding of the clamp on a dovetail when its tightening knob is loosened. The rings have large and ergonomic knobs for easy and secure attachment, even in the dark. Nylon tips on the three hand-tighten adjustment/centering screws in each ring will not mar the finish on your guide scope.
Optional accessory mounting plates (shown below) are available for installing the rings on any Celestron 8” through 14” optical tube. The rings will also mount directly on the D-plates supplied with Astro-Tech 10” and 12” Ritchey-Chrétien astrographs, as well as any other D-plate equipped optical tube.
