Astigmatism correction for Tele Vue eyepieces

The Tele Vue Dioptrx Astigmatism Correcting Lens - 3.00 diopter optic attaches to compatible Tele Vue eyepieces and corrects up to -3.00 diopter of astigmatism. It is intended for astronomers who want sharp full-field views without wearing eyeglasses during observing sessions. The lens locks onto over 20 long eye-relief Tele Vue eyepieces and rotates for precise alignment to the user's vision axis. Engraved barrel letters provide a reference for repeatable orientation.

Diopter range and eyepiece compatibility

The unit supplies a -3.00 diopter correction and is one step in a series available from 1/4 up to 3.5 diopters in quarter-diopter increments. It fits only the designated long eye-relief Tele Vue eyepieces; other eyepieces or brands are not supported. Observers whose astigmatism exceeds 3.5 diopters will need a different correction solution not covered by this product line.

Optical construction and handling

Multi-coated glass housed in anodized aluminum with a rubber eyeguard delivers durable optical performance and comfortable eye relief. The tool-free locking mechanism secures the lens to the eyepiece top for stable viewing. No power, cooling or electronic interface is involved; the accessory adds minimal mass and requires no maintenance beyond normal optical cleaning.

Questions about this item

Will the Dioptrx 3.00 diopter lens fit the Tele Vue eyepieces I already own?

It attaches and locks onto the tops of over 20 long eye-relief Tele Vue eyepieces, so most recent models in that range are compatible.

How can I verify the lens is aligned correctly for my astigmatism after installing it?

The barrel has engraved reference letters; rotate the lens while observing a star until the image is sharpest, then note the letter position for future sessions.

Does the package include an eyepiece or only the correcting lens and its built-in rubber eyeguard?

Only the Dioptrx correcting lens with its integrated rubber eyeguard is supplied; a compatible Tele Vue eyepiece must be purchased separately.
