Telrad Extra Mounting Base
Easily Move Your Telrad Between Telescopes
If you own more than one telescope, an extra Telrad mounting base is a simple and affordable way to share a single Telrad Reflex Finder across multiple setups. Instead of buying multiple finders, just install a base on each scope and slide your Telrad on and off as needed.
The Telrad base is a rugged, lightweight plastic rail designed to mate perfectly with the standard dovetail mount on the underside of every Telrad finder. Installation is easy—no drilling or permanent modification is required. Each base includes a strip of double-sided adhesive tape for secure attachment to your optical tube, plus screw holes should you want to attach it to a Sonotube Dobsonian or equatorial mount optical tube. The two plastic locking thumbscrews make removing and attaching a Telrad to the already -installed base a matter of moments. The dovetail bracket positions the Telrad accurately and repeatably each time the finder is installed, making recollimation rarely necessary. Once installed, the base holds your Telrad finder snugly in place during observing sessions but allows tool-free removal for storage or transfer to another scope.
This is the exact same mounting base that ships with a new Telrad unit, so it's fully compatible with all standard Telrad reflex finders.
Whether you’re switching between a Dobsonian and a refractor, or just want the flexibility to move your Telrad from home to the field, this extra base gives you seamless, repeatable alignment and convenience without the added cost of a second finder.
