The dual-speed Crayford focuser features a focus control with 1:1 and 10:1 speed ratios allowing superbly smooth and precise focusing at all magnifications. The focuser attaches to the telescope via four holes positioned in each corner of the mounting plate. The overall length of the focuser (including the 1.25" to 2" eyepiece adaptor), measuring from the edge of the mounting flange is 2 inches(50mm). Racked out the total focuser tube extension(again minus the eyepiece adaptor) is 4.75 inches (120mm). The mounting pedestal measures 3.5 x 4.5 inches (90 x 115mm) and is 1/2 inch (13mm) deep at it's thickest point. The focuser is fully (360 degrees)rotatable when fitted to the telescope. The focuser has adjustable tension and stiffness making it ideal for carrying heavier eyepieces and cameras. And allows the focus point to be locked by actually disengaging the focus control knob via a thumb knob. This is a beautifully engineered focuser and it functions every bit as well as it looks!

ED Apochromatic 127mm f/7.5 Refractor OTA Telescope - 99% Dielectric-Coated 2" Diagonal w/1.25" Adapter - 8x50 Viewfinder - 2-Speed Focuser w/Adjustable Tension & Lock - Removable Dew Shield - Front/Rear Dust Covers - Cradle Rings w/Handle - Universal Saddle Plate - Deluxe Heavy Duty Case - Explore Scientific U.S.A. Five Year* Limited Warranty (* One-Year Limited Warranty, Extendable to Five Years (transferable) Upon Registration)- Note: Eyepieces Sold Seperatly, Mount Not included.Explore Scientific's 127mm f/7.5 telescope is an air-spaced triplet ED APO refractor telescope that utilizes Hoya ED glass. This telescope comes equipped with a 99% dielectric-coated 2-inch diagonal and also includes a 8x50 viewfindermaking it easy while searching for celestial objects. The designers of the Air Spaced Triplet ED Apo Series pursued to produce top-quality refractors with lasting value. The optical solution was to provide atraditional air-spaced design mounted in a rugged, adjustable lens cell. This design, shaped from experienced craftsmanship and polished from genuine HOYA FCD1 (Dense Fluor Crown) ED (Extra-low Dispersion) glass, a critical element to produce images that refractor afficianados know can only be obtained with a high-quality true apochromat. The owner of an Explore Scientific ED Apo will appreciate the attention to detail and the standard hardware which includes a precision 10:1 two-speed focuser, a 2" 99% reflective dielectric diagonal, an 8x50 erect-image, illuminated-reticle viewfinder, and a deluxe case. You can be confident that thequality and construction of these telescopes will allow heavy use for many yearsand are backed with a transferrable Five Year USA Limited Warranty. EMD (Enhanced Multilayer Deposition) Coatings eliminates light scatter and maintains image contrast. Contrast is further enhanced with multiple baffles that mask and deflect unwanted stray light. All Explore Scientific ED Apochromatic Refractor telescopes include a precision Ten-to-One, Dual-Speed Focuser as standard equipment. The eyepiece holder uses acompression ring to prevent the eyepiece or camera barrel from scoring. One of the bonuses of ownership of a refractor is that, compared to standard reflector telescopes, they almost never require re-aligning of the optics (collimation). However, any telescope that is subjected to shock may require optical alignment. Removing the dew shield, you can access the alignment screws, which you can adjust yourself by referring to the instructions. You can also send it to Explore Scientific's Service Center for alignment. A standard service charge applies. Provided as standard equipment, Explore Scientific's Two Inch Dielectric Diagonal incorporates a light-weight, one-piece diagonal body that securely cradles the precision polished diagonal flat mirror, insuring precision alignment. Ultra-high reflective coatings (99% reflective) composed of multiple thin layers of dielectric material delivers maximum light output. The Explore Scientific 8x50 produces a wide 6° field of view and allows precision focus of both main objective and eyepiece illuminated reticle. A precision polished roof prism produces images that are right-side-up, left-to-right correct. In other words, things are not upside-down and backwards like most viewfinders.

Just say NO to T-Rings! As the CCD chips in our DSLR cameras get larger it is ever more important to have an unobstructed light path to prevent vignetting. The manufacturers of high end scopes wisely put 2" eyepiece ports on them. Why then do we insist on putting a 1.5" bottleneck between your camera and telescope? Answer: T-Rings have been around for decades, a legacy standard as outdated as 300 baud modems. They exist not because they are the best solution for imaging, but because they are the best solution for manufacturing. After all it's much easier to spin a standard thread on all adapters, regardless of telescope port size or camera brand. The T-Ring may be convenient but it is simply out of its league on a scope with a 2" eyepiece port. True-2TM is a true 2" prime focus adapter that takes you directly from the cameras bayonet mount to a 2" Barrel with as few wasted photons as is possible, adding as much as 10mm more clear aperture over legacy adapters! The largest clear aperture of any adapter on the market. And it costs little more than you would spend on a quality T-Ring and 2" T-adapter. Baffled to reduce reflections and threaded for 2" eyepiece filters. Now also available with or without an undercut on the barrel. Don't choke the photons out of your camera with an inferior adapter! This listing fits all Nikon Film or Digital SLR & DSLR Cameras including (digital models) D1, D2, D3, D3S, D3X, D35, D40, D40X, D50, D60, D70, D80, D90, D100, D200, D300, D300S, D700, D3000, D3100, D5000, D7000.

All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial CCD detectors, allowing stars to be in tight focus to the very edge of the chip Internal GPS The CPC Deluxe HD Series' internal GPS receiver automatically downloads the date and time from orbiting satellites and pinpoints its exact location on Earth. This eliminates the need for you to manually enter the date, time, longitude and latitude. Celestron's Revolutionary SkyAlign Once the CPC's internal GPS has established the telescope's position, aligning the telescope is as easy as 1-2-3! Simply locate and use the hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars you may even pick the Moon or bright planets! Celestron's NexStar software technology will model the night sky to determine the position of every star, planet and celestial object above the horizon. Once aligned, the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database. Celestial Object Database The CPC database contains over 40, 000 celestial objects including Messier objects, the Caldwell Catalog, as well as NGC Galaxies, nebulae and planets. User-definable filter limits make navigating through this expansive database quicker and easier. Filter Limits let you filter out objects that are outside of your local horizon (ie, if trees or mountains were in the way). There's also "Solar Sys Align" that lets you align on the Sun or Moon for daytime observing -- it is easy to use this to see planets or bright stars in the day. Luminos Eyepiece CPC Deluxe 925 HD comes with Celestron's top of the line, wide field eyepiece.
