Celestron 15x70 SkyMaster Pro Binoculars for Astronomy SkyMaster Pro binoculars are the ideal choice for amateur astronomers or anyone that observes at great distances. Compared to lower-priced large aperture binoculars, SkyMaster Pro uses superior optics, coatings, internal parts and housing materials. With large objective lenses, BaK-4 prisms and fully multi-coated optics utilizing Celestron’s proprietary XLT coating technology, the view through a SkyMaster Pro is second to none at this price point. Massive Objective Lenses - The 70 mm objective lenses have tremendous light gathering capabilities, delivering superior low light performance, even in the dimmest conditions. Choose SkyMaster Pro for use at dusk, dawn and nighttime astronomical viewing. Fully Multi-Coated Optics and BaK-4 Prisms - Every air-to-glass surface is multi-coated with Celestron’s proprietary XLT coating technology. These coatings coupled with BaK-4 prisms increase light transmission through the optical path and deliver crisp, high contrast images with outstanding resolution. Built in Tripod Adapter - The built in tripod adapter of the SkyMaster Pro 15x70 allows the binocular to be attached to a tripod for added stability during longer viewing sessions and also allows a red-dot finder to be attached to it utilizing the included RSR “Reflex Sight Ready” Rail. When properly aligned with the binocular, the red-dot finder will allow objects to be brought into view quickly. RSR “Reflex Sight Ready” Rail - The tripod adapter included with the SkyMaster Pro not only allows the binocular to be attached to a tripod for added stability during longer viewing sessions, but also includes a removable rail for attaching a red dot finderscope. When properly aligned with the binocular, a red-dot finder helps you locate objects quickly and center them in the binocular. Lightweight, Waterproof Construction - A polycarbonate and aluminum housing makes SkyMaster Pro durable and lightweight. The housing’s protective rubber armor is extremely rugged and can stand up to tough use. The fully waterproof housing for use in all weather conditions provides peace of mind when unexpected weather rolls in. The housing is also filled with dry nitrogen gas to prevent the internal lenses from fogging when moving between extreme temperatures or when using the binocular in damp conditions. Extended Eye Relief - 17 mm of eye relief allows for comfortable viewing for both eyeglass and non-eyeglass wearers. Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses on. For those that do not wear eyeglasses, the rubber eyecup positions the users eye behind the eyepiece at the correct distance for optimal viewing. Enhanced Magnification - Bring distant objects into view with 15x magnification—great for observing celestial objects in greater detail, searching for wildlife in the brush or viewing a distant object on the horizon. Celestron 51630 Star Pointer Telescope Finderscope, Black The Celestron Star Pointer Finderscope is the way to go if you want the easiest way possible to locate an object and center it in your eyepiece. A red dot finder, unlike an optical finder, has 1x magnification, displays a super wide field of view, and keeps the sky right side up and left-to-right correct, matching what you see with your unaided eyes. An LED creates a red dot, superimposed on a viewing screen, so you simply point the Star Pointer to the area or object you wish to observe, look through your eyepiece, and if properly aligned, the area in and around place you pointed the red dot will be centered in the field of view. If you like the idea of having some magnification, try installing both a red dot and optical finder on your telescope. Schmidt-Cassegrain and EdgeHD telescopes have multiple mounting bracket holes so you can get the best of both worlds. Just make sure to align both of them correctly, and you’ll get the best use out of each of your finders. How to Align the Star Pointer Finderscope The first time you use your finder, you need to align it. This one-time setup procedure should be done during the day. Take the telescope outside and find an easily recognizable object, such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, but at least a quarter mile away. Move the telescope left and right or up and down so that it is roughly pointing at the object. Look through the telescope using your low power eyepiece and move the telescope until the object you chose lies in the center of the view. Once the object is centered in your eyepiece, turn on the red dot. With your head positioned about a foot behind the finder, look through the round lens of the finder and locate the red dot. Without moving the telescope, use the two adjustment knobs located on the side and underneath the finder. One controls the left-right motion of the dot. The other controls the up-down motion of the dot. Adjust both of these until the red dot appears over the same object you are observing in the eyepiece. Your finder is now aligned and should not require realignment unless it is bumped or dropped. You can even take the finder off the telescope and reattach it while preserving alignment.
