TeleVue - 2.00 DIOPTRX Astigmatism Correcting Lens

Your telescope’s focuser is used to compensate for your near- or far -sightedness; DIOPTRX™
compensates for your astigmatism. These units attach and lock onto the tops of over 20 long
eye-relief Tele Vue eyepieces to achieve the sharpest full-field viewing possible. DIOPTRX™
models are available in ¼ diopter steps, from ¼ up to 2½ diopters, and are rotatable for tuning
to the best orientation. A series of engraved letters on the barrel helps to monitor orientation.
Simply choose the DIOPTRX™ model that matches your eyeglass prescription for astigmatism. All
lenses are multi-coated glass in anodized aluminum housings with rubber eyeguards.
