Product Description

This is a set of two adjustable rings that are made to mount our F50 or F60 finder scopes onto a larger telescope for use as a finder and/or guide scope. Each ring has three stainless adjustment screws with nylon tips. Each ring is mounted to a dovetail shoe that will slide onto either a Losmandy, Stellarvue or Vixen rail. In the picture shown, the ring systems are attached to a separately available Losmandy style rail. 

r68lv-on-scope-400.jpgThis ring system has an inside diameter of about 76 mm. This is the perfect size for holding our finders, our former SV60EDS Apo and other small telescopes with tubes that are under 65 mm in diameter. Guide scopes are used as both super finders and for guiding the main telescope when doing astro-photography. 

When mounting a guide scope on top of another telescope, it is necessary to use adjustable rings. Adjustable rings allow the guide scope to be moved slightly in relation to the main telescope. This is necessary because if non-adjustable hinged rings are used, the two telescopes will never be pointed in precisely the same direction. When using a guide scope as a super finder, adjustable rings will allow the user to make sure each telescope is centered on the same object. When doing astro-photography, adjustable rings will make it possible to point the guide scope at a relatively bright guide star while the main telescope is centered on the object being photographed. 

In order to use this system, mount a Losmandy, Stellarvue or Vixen sized rail of the proper length atop the main telescope's hinged rings. Slide the two rings onto the rail as shown. Insert the guide scope into the rings and align the guide scope with the main telescope using the three nylon tipped thumb screws on each ring.

Stellarvue rails are sold separately. Choose a rail that is the proper length to work with the dual rings on your telescope. In the example to the left an SV130 Apo is mounted to the mount using a Stellarvue TP013 Losmandy-sized rail. Since the TP013 is used on the bottom, mount another TP013 on the top as shown. Slide the rings and guidescope onto the top TP013 rail.
