Bausch & Lomb 6mm Orthoscopic Eyepiece - 1.25" in BOX (Pre-owned)

An eyepiece with a 6mm focal length is likely to provide relatively high magnification when used with a telescope. The term "Orthoscopic" refers to a specific design of eyepiece that aims to provide good image quality, especially for planetary observations. Orthoscopic eyepieces are known for having a relatively simple design, providing a wide field of view, and being well-suited for planetary and lunar observing.

The 1.25" barrel size is a standard size for many telescopes, and it refers to the diameter of the eyepiece barrel. Telescopes often use either 1.25" or 2" eyepieces, and the choice depends on the telescope's design.
