I have puchased a WO zs66sd and it came with the base from the 1st gen WO rdf I need to use the base as i tried your Baader std base because of the curved bottom but its to wide and contacts the screw holding the view finder in place.Could you tell me the width of the top pce im hoping its not more than 15mm then i can slot it in the base im forced to use, as the gun rail is 11mm im hoping this is the case.

Can you please tell me the center to center spacing between the two threaded holes for M5 hex screws that attach RDM to the dovetail base? I am planning to order a custom V-style clamp that will attach the RDM to a vixen dovteail bar, and will need this hole spacing to have the counterbored holes machined into the part.

This universal Red Dot Mount RDM is made of sturdy metal and is designed to use red dot finders with Weaver standard 11mm gun rail with a V-shaped dove-tail which fits most finder-shoes of Celestron, Sky-Watcher, Vixen and Bresser telescopes. 70 mm height provide efficient "face-space" between telescope and red dot finder, even with Newtonians. The V-shaped base-part can be removed for mounting the rail part straight onto third party platforms.

RDM adapter for Vixen dovetail bar
I have a side-mounted 92mm refractor that I installed a second vixen dovetail bar on top of the rings that doubles as a carry handle and an attachment point for accessories. In order to attach Baader SkySurfer V red dot finder to the dovetail bar, I used Baader Universal RDM with the Dovetail Base removed and screwed to a small V-style dovetail adapter that was drilled with a pair of counterbored M5 holes spaced at 20mm apart. In the future I also plan to use the same adapter to attach a 60mm Baader Multi-purpose Vario Finder to the dovetail bar.

The accessory adapter can slide and clamp along the entire length of the dovetail bar allowing for great flexibility in balancing the telescope, in lieu of attaching heavy accessories to the focuser end which tends to make the telescope tail-heavy. I am very satisfied with this setup.

To note: When I had trouble finding the hole sizes and spacing for the two screws that attach Universal RDM to the Dovetail Base, within hours of my submitting a product question, Baader staff reached out to me and provided exceptional support, including adding images to the product info page that show the hole pattern. This is an A+ company that stands 100% behind their products and the amateur astronomy community.
