General Brand BT831 Overview

This Pentax M42/Universal Screwmount Lens to Telescope Adapter - to Convert Lens to Telescope allows you to convert your "universal" (M42) screw lens into a telescope. By attaching this eyepiece to the back of a lens you can now view directly through the lens, as you would with any standard telescope.

Not ideal for terrestrial viewing, since no erecting prism is included in this design.
