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.

Hello This product has 3 types of mounts. I checked what you have. I use a Nikon F mount. I think one of the three will suit me. Will you confirm?
