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 from ¼ to 3½ diopters (¼ steps from ¼ to 2½ diopters, then ½ diopter steps to 3½-diopters), and are rotatable for tuning to the best orientation. A series of engraved letters on the barrel helps to monitor orientation. All lenses are multi-coated glass in anodized aluminum housings with rubber eyeguards.

You're more likely to see a sharper, higher contrast image, compared to glasses because:

•The DIOPTRX™ is always completely aligned to the eyepiece optics, eliminating aberrations from a decentered mismatch of eyeglass power and astigmatic axis.

•DIOPTRX™ can be rotated to exactly compensate for the astigmatic axis angle in real time, since both head angle and age can vary your eyesight astigmatic angle.

•DIOPTRX™ likely has better multi-coatings than eyeglasses, and certainly is better in transmission and reflection reduction than uncoated eyeglass.

•DIOPTRX™ is more likely to be cleaner than eyeglasses, which may have scratches and smudges from constant use and wear and tear.

•DIOPTRX™ allows seeing your normal maximum contrast that eyeglasses can diminish (remove your eyeglasses and see how contrast improves in normal vision).

Looking at your eyeglass prescription, simply choose DIOPTRX™ to match the cylinder (astigmatism) value of your preferred viewing eye. Ignore spherical and axis values and ± signs. Maximum pupil size decreases with age and this decrease the visibility of astigmatism. See charts above.
