Astromania or Svbony Rings for 50mm Finder/Guide Scope

Replaces the bulky rings that come with the Astromania 50mm guide/finder scope. Obviously non-adjustable, but I prefer the more secure/stable mounting of the guide scope.

Require four holes to be tapped 5mm x 0.8

Reuse the dovetail and two metric cap screws that came with scope, pick up two more 5mm x 0.8 x 15mm long cap screws from your local hardware store.
