Enhanced Clarity for Astigmatism

The Tele Vue Dioptrx 1.50 diopter lens corrects astigmatism for sharper views through compatible Tele Vue telescopes. It matches a -1.50 prescription to eliminate the need for glasses during observing sessions. This accessory is designed for astronomers who want full-field clarity without wearing corrective eyewear at the eyepiece.

Precision Optics and Light Transmission

Multi-coated glass surfaces maintain high light transmission and image contrast across the field of view. The anodized aluminum housing adds negligible weight to the eyepiece assembly and does not alter the telescope's thermal balance. No power is required and the passive optical element introduces no noise or vibration during use.

Rotatable Mount and Durable Build

The lens attaches securely to over 20 long eye-relief Tele Vue eyepieces via a threaded barrel with engraved orientation markers. Rotatable design allows fine-tuning to the exact astigmatism axis for each observer. Rubber eyeguards protect the glass and improve comfort during extended viewing, while the aluminum body resists corrosion and wear in outdoor conditions.

Questions about this item

How do I attach the Dioptrx 1.50 lens to my Tele Vue eyepiece and which step is often missed?

Slide the lens onto any of the 20 compatible long eye-relief eyepieces, then rotate it until the engraved letters align with your prescription axis; the rotation step is the one users forget.

What part of the Dioptrx 1.50 will need replacement after extended use?

The rubber eyeguards on the anodized aluminum barrel wear down over time and are the only component expected to need replacement.

At what diopter value does the Dioptrx range stop correcting astigmatism?

The series tops out at 3.5 diopters, so prescriptions stronger than that cannot be matched with this accessory line.
