TeleVue 6mm 1.25" 72° Field Delos Eyepiece

The 6mm TeleVue Delos is designed for no-holds-barred high power/high contrast solar system and deep space observing with any telescope. It has a long 20mm eye relief that makes it ideal for eyeglass wearers. The majority of eyepieces in this focal length range have much shorter eye relief that makes them problematical for eyeglass use, but that is not an issue with the Delos. With 20mm of eye relief, its full 72° apparent field is easily usable with glasses.

There is an adjustable height eyeguard with a soft rolldown eyecup to shield the eye from ambient light (from a neighbor's security light, for example) and improve the image contrast. The eyeguard height can be locked in place at any point desired. The rubber eyecup rotates for use with TeleVue Dioptrx astigmatism correcting lenses.

As a longer eye relief 72° field version of the acclaimed 100° field 6mm TeleVue Ethos, the 6mm Delos has all the virtues that astronomers have come to expect from an Ethos: high contrast, a neutral color balance, and full field sharpness - with well-controlled astigmatism, field curvature, lateral color, angular magnification distortion correction, and low pupil sensitivity (kidney bean effect) for daytime use.

The 6mm Delos has a 1.25" barrel that is threaded for standard 1.25" eyepiece filters. A safety groove is machined into the chrome barrel to engage your focuser thumbscrew. This will help prevent the eyepiece from falling should the thumbscrew accidentally loosen while observing. The main eyepiece barrel is narrow enough to comfortably use a pair of 6mm Delos in a binoviewer. Rubber grip rings provide a sure grip in cold weather when wearing gloves or mittens. Dust covers are provided for both ends of the eyepiece.
