SVBONYDovetail Base for Finder Scope Ideal for Installation of Finder Scope Fully Metal Bracket Base 42mm Dovetail for Optical Telescope

These are just what you need to add a finder to your telescope. If the finder already has the foot to fit the shoe, great, you have an extra foot. If you're adapting an air gun sight or other sight, then you can attach it to the foot without drilling - it has a nice slot that adapts to many layouts. This is well-made, especially for the price.

High end scopes like AstroPhysics focusers do not have a finderscope shoe. However this shoe has nearly the exact same diameter as AP focsers, so a bit of silicone will affix it to the focuser body, and you can then use any Orion or Vixen or Synta style finderscope available. It’s also black and matches the AP focuser body. So if you use black silicone, on a black focuser on a black quick release shoe it looks very good and almost factory when done.

Worked perfectly to attach a Coronado PST to my 5 inch Mak.

This is a very useful item for mounting standard telescope finders, 6x30, and 8x50. One can easily remove the finder from this base by just loosening a thumbscrew. When the finder is replaced, the alignment remains perfect. Also, you'll love the black, anodized finish.

Just what I needed, a small dovetail system for a finder on my telescope. Highly recommended

This fits perfectly on the dew shield of my refractor. The curvature is just perfect and seats air tight. All I needed to do is use double sided tape and it sticks perfectly.Svbony got the curvature correct on this one.This is used to move my red dot finder forward so I when viewing at zenith, it won’t be affect my navigation

I usually have nothing but praise for Svbony products. Very good quality for the price. However, no praise can be given on this one. The hole pattern is way different from the Svbony 503 scopes, about a four millimeter difference. Not only that, but it would not fit two other scopes I own. The screw spacing on the scope is of a standard size and shoes I have from three other companies that I have (including ZWO and Baeder fit the scope. I wanted a curved shoe to fit my scope profile so I ordered these.
