About the TeleVue Eyeguard Extender... Many TeleVue eyepieces, such as Radians, Nagler type 4, 55 Plossl and 41 Panoptic have adjustable height eyeguards to permit comfortable viewing with or without eyeglasses. Other eyepieces such as the TeleVue 35 Panoptic, 27 Panoptic, 40 Plossl, 32 Plossl have long eye relief that is comfortable for eyeglass wearers, but the eye relief may be uncomfortably long for some users without eyeglasses. Enter the TeleVue "Eyeguard Extender"! TeleVue 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 2 units 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 TeleVue eyeguard extender is black anodized aluminum with anti-reflection threads. Remove rubber eyeguard to reveal bare eyeguard flange. Mount Eyeguard Extender and you'''re in business! The TeleVue Eyeguard Extender attaches to the top of your eyepiece with the simplicity of a DIOPTRX 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 TeleVue Eyeguard Extender in its place, screw-down the inner ring until the Eyeguard does not slip off.
