Televue Eyeguard Extender, Twist-on Style EGE-0020 raises the telescope eyeguard position by 8mm and includes a rubber eyeguard and eyepiece cap in case yours is lost or damaged and is the must needed Televue Telescope Accessory for any serious astronomer. Televue eyeguard Extendors are stackable: for example 2 units add 16mm height and make a 40mm Plössl very comfortable for solar viewing by blocking out stray daylight to maximize contrast in white light or hydrogen-alpha viewing. This telecsope accessory is made from black anodized aluminum with anti-reflection threads. The Eyeguard Extender 0020 from Televue attaches to the top of your telescope eyepiece with the simplicity of a DIOPTRX corrector. It has two rings that thread together to clamp on the telescope eye piece: 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 Tele vue Eyeguard Extender in its place, screw-down the inner ring until the Eyeguard does not slip off.
