Glass Reticle, Telescope reticles

الوصف

A reticle is a glass disk with an etched measuring pattern. These glass reticles offer greater stability than film reticles which can bend, warp, and easily be damaged. Patterns are low reflection chromedeposition for high contrast and easy readability.

This reticle has a microruler and a microprotractor, plus a grid ruler for measuring half lengths. The grid ruler is just above the protractor, giving you a good reference for aligning the table when measuring crown and pavilion angles.
