Dioptrx 0.50 Diopter Astigmatism Corrector	$98.00
[DRX-0050]

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 1/4 to 3 1/2 diopter (1/4 steps from 1/4 to 2 1/2 diopters, then 1/2 diopter steps to 3 1/2-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.

HOW TO CHOOSE DIOPTRX™ MODELS

Your prescription may look like this, with different numbers.

		SPHERICAL	CYLINDER	AXIS
Right Eye	O.D.	+1.5	-0.5	45
Left Eye	O.S.	-0.5	+1.5	135

Ignore spherical and axis values.
Ignore all ± signs.
Simply choose DIOPTRX™ to match the cylinder (astigmatism) value of your preferred viewing eye. In the example above, you would choose 0.5 diopter model for your right eye and 1.5 diopter model for your left eye.
