Programmable TELRAD Style Finder Scope

#Programmable TELRAD Finder Scope#

A Telrad is a type of collimating reflector sight used as a viewfinder for telescopes and other optical equipment. This is a modified, low cost Telrad design with a programmable reticle which can overlay shapes and text onto the viewfinder. Instead of a glass lens, it uses a credit card sized Fresnel lens as a collimator. Mounts are compatible with [claus57's weaver/picatinny rail mounts](https://www.thingiverse.com/thing:3125380) as opposed to proprietary telescope mounts, allowing it to be mounted to anything with a rail or [rail adapter](https://www.thingiverse.com/search?q=telescope+rail+adapter&type=things&sort=relevant).
