Viewing through SkyMaster Pro ED binoculars is comfortable for eyeglass and non-eyeglass wearers alike, thanks to the retractable eyecups and nearly 16mm of eye relief. Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses by twisting the eyecups down. For those who do not wear eyeglasses, the eyecups position the user’s eye behind the eyepieces at the correct distance for optimal viewing.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWays to Observe:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Celestron SkyMaster Pro ED binocular is tripod-adaptable.

Adding the right filter can deliver game-changing views for terrestrial and celestial observing. For terrestrial observation, filters can reduce the brightness of sand, snow, and water. For nighttime viewing, filters can cut glare, minimize eye strain, increase contrast, and even combat the effects of light pollution. Remember, the binocular needs a set of two filters.
