Increase your viewing comfort through Tele Vue telescope eyepieces with the Tele Vue Eyeguard Extender!

Many Tele Vue eyepieces, such as Radians, Nagler type 4, 55mm Plossl, 41mm Panoptic have adjustable height eyeguards to permit comfortable viewing with or without eyeglasses.

Other Tele Vue eyepieces such as 35mm Panoptic, 27mm Panoptic, 40mm Plossl and 32mm Plossl have long eye relief that is comfortable for eyeglass wearers, but the eye relief may be uncomfortably long for some users with eyeglasses.

The Tele Vue Eyeguard Extender raises the eyeguard position by 8mm, and includes a rubber eyeguard and eyepiece cap in case yours is lost or damaged. Units are stackable: for example using 2 Eyeguard Extenders add 16mm height and make a 40mm Plossl very comfortable for solar viewing by blocking out stray daylight to maximize contrast in white light or hydrogen-alpha viewing.

The Tele Vue Eyeguard Extender attaches to the top of your Tele Vue eyepiece with the simplicity of a DIOPTRIX ™ corrector. It has two rings that thread together to clamp on the eyepiece: an inner-ring that holds the rubber eyeguard and outer ring that slips over the top of the eyepiece. Starting with the inner-ring backed off from fully tight, take off your existing rubber eyeguard, place the Eyeguard Extender in its place, then screw-down the inner-ring until the Eyeguard does not slip off.
