Stellarvue R50D - 50mm Finderscope Rings on Dovetail Stalk
R50D Dual Ring Dovetail Stalk 50 to 60 mm Finderscope Mount
Are you interested in mounting a 50 to 60 mm Stellarvue finder scope to an imported reflector or Chinese focuser? This is the accessory for you.
The 1.18-inch wide dovetail base fits most dovetail shoes found on Chinese focusers (like the ED80) and import reflectors. It will work in dovetail bases that are this size and wider at the base.
Simply attach the quick release dovetail base, insert your finderscope and secure with the non-marring nylon-tipped stainless steel collimation bolts. Once the optics are aligned, you just use the quick release feature at the end of your observing session and the dual ring assembly keeps your collimation secure for the next use.
Image Note: Telescope, finderscope, diagonal, and eyepiece are shown for use purposes only and are sold separately.

Works but could have better mounting security
The rings hold a 7x50mm finderscope fine. However, the dovetail suffers from two issues. 1) the width of the dovetail was slightly too thin to allow the TPO dovetail shoe screw to tighten against the dovetail. This allowed the rings bracket to slide in the shoe as the telescope was slewed. I had to add some padding to the dovetail to get a better fit in the shoe. Unfortunately, the dovetail does not have a STOP to prevent the rings from sliding as the telescope is slewed. If the shoe screw works loose the rings and the attached finderscope can slide off of the telescope and hit the ground. Not a good design.
exercise in frustration!
This item is one to be avoided!! I installed a Stellarvue F50M 9x50 finder on it and it took me ages to align the finder with my 12 dob!! The 6 screw system makes the whole thing VERY difficult to align. Cannot be centered easily and it makes the finder slip sometimes if you forget to tighten one of the screws! I cannot believe they are still producing this total failure of a system..The original cylinder bracket that came along with the dob is MUCH better BUT the F50M won't fit inside the cylinder so i HAD to use that silly 6 screw system. I am planning to get rid of it the soonest possible! Don't mess with it, it will get to your nerves!
I purchased this finder bracket for a Celestron C102mm wide view spotting scope I own. Very pleased with the purchase. Excellent overall quality, all metal construction. Quick release feature maintains collimation as advertised. This is made to mount up to a 60mm finder. I mounted a 50mm scope in this but very much like the extra wiggle room I had with the 6 long set screws. Made alignment a snap. I purchased this across the counter at OPT. Staff was very helpful, allowing me to check the fit of the base on a C102 they had on the floor prior to puchase. Thanks again.
