- Whether you're skywatching with just your eyes, with binoculars, or with a telescope, a planisphere star chart like the Star Target is an essential tool you'll use time and time again. It's an invaluable reference tool for learning the constellations, identifying stars, and locating popular bright celestial objects such as galaxies, open and globular star clusters, and nebulas.The easy to use Orion Star Target Planisphere is a rounded star chart map which you rotate in its housing to dial in the date and time. Once the preferred date and time is dialed in, the Star Target displays a nicely detailed map of the current night sky. You can then rotate the Star Target to get a sneak peek of what objects will become visible as the night goes on, or to see when objects will be ideally positioned in the sky for observation through a telescope or pair of binoculars. It's easy to plan an entire night of stargazing fun in advance with the handy Orion Star Target, since it can tell you when and where your favorite objects and constellations will be visible. The affordable Orion Star Target Planisphere features a detailed star map drafted by renowned celestial cartographer Wil Tirion. It shows all constellations visible from mid-northern latitudes ranging from 40-deg North to 60-deg North, as well as the locations of 100 showpiece star clusters, nebulas, and galaxies for viewing with binoculars or a telescope. The Star Target's map works year-round and year after year.The Star Target is a must-have for any stargazer, regardless of skill-level, but it is especially useful for beginners. The planisphere is made of coated, dew-resistant cardboard, and measures 8-3/8" in diameter, so it's easy to stow just about anywhere. You just dial in the date and time, and -- voila! -- Star Target displays a current map of the night sky. On the back are simple directions plus viewing tips and a calendar of annual meteor showers. A must for any stargazer, especially beginners.Orion tele-extenders permit high-magnification "eyepiece projection" photography of the Moon and planets with a Schmidt-Cassegrain telescope. Orion tele-extenders are designed to fit all Celestron and Meade Schmidt-Cassegrain telescopes. Made of anodized aluminum, the tele-extender fits over a 1.25" telescope eyepiece, with one end threading onto the eyepiece holder (visual back) of the telescope, and the other end threading into the T-ring (sold separately) attached to your DSLR camera body. This Standard Tele-Extender is a fixed-length cylinder that provides a single projection magnification depending on the focal length of the eyepiece you use. Some 1.25" telescope eyepieces have housings that are too wide to fit inside the tele-extender.A T-ring converts a SLR or DSLR camera mount to a standard T-thread. All camera adapters and universal camera adapters will fit this T-thread. This wide (48mm) T-ring supports full 35mm format cameras. A wide format T-ring is needed for astrophotographic applications using a Nikon DSLR or SLR camera and a focal-reducer / corrector lens.The Orion Zero Profile Camera Adapter couples your camera to a telescope for prime-focus astrophotography. The zero-profile design provides closest possible in-travel for cameras in any 2" telescope focuser. Many prime focus camera dapters for use with astrophotography telescopes have housings which can add distance between your imaging camera and the focal plane. This can make it difficult to achieve focus with certain astrohphotography camera and telescope combinations. Not so with the Orion 2" Zero-Profile Prime Focus Camera Adapter, which couples your camera to a telescope for prime-focus astrophotography. This handy adapter threads directly into the T-ring (sold separately) for your single lens reflex/digital single lens reflex (SLR/DSLR) camera body and is also threaded for 2" telescope filters.The Orion Zero Profile Camera adapter fits 2" telescope focusers on refractor and reflector telescopes.

The included foam-lined plastic case will keep your Dark Frame Imaging Filter safe during transport and storage.This versatile filter acts like a dimmer switch for your telescope, toning down the brightness of the Moon or planets to a level that is comfortable. The reduction in brightness and glare unmasks detail in your viewing subject and greatly improves contrast. The filter consists of two high-grade glass polarizing filters in a rotating cell that allows you to adjust the amount of light transmission from 1% to 40%. Such control is highly desirable for lunar observing because the Moon's brightness varies with its phase. The filter is great for terrestrial observing too, especially on sunny days. The filter has an anodized aluminum cell, which threads into the barrel of any standard 2" eyepiece. Storage case included.The S-II filter passes light at the 672.4nm wavelength (the Sulfur-II line in the deep red end of the visual spectrum) with very high 90 percent transmission and a bandpass of 7nm. It complements the Orion H-alpha and Oxygen-III extra-narrowband filters, which together allow advanced tricolor imaging of emission nebulas with the StarShoot Deep Space Monochrome CCD Imaging Camera or other monochrome CCD cameras. So if you're ready to go beyond RGB imaging and capture your favorite nebulas in a revealing new light - no matter how light-polluted your skies -- add our S-II (and O-III and H-alpha) Extra-Narrowband filter to your imaging arsenal! Includes protective plastic case.You can't turn up the luminosity on nebulas, but you can crank up the contrast between them and the sky to reveal more of their wondrous detail. Our Oxygen-III filter provides extremely selective filtration to bring out elusive detail in diffuse and planetary nebulas. It does so by transmitting close to 90% of the light corresponding to the two oxygen-III spectral lines at 496nm and 501nm while completely blocking virtually all other wavelengths. The results are remarkable. You'll see more detail than you ever could before in nebular gems such as the Swan, Ring, Dumbbell, Helix, and Eagle, to name a few. The O-III provides an even greater contrast boost on some objects than the UltraBlock narrowband filter. And for nebulas, every little bit helps! Try the O-III with a low-power 2" eyepiece and take in the whole Veil Nebula. Wow!This useful telescope eyepiece filter transmits 25% of incoming light. It's ideal for viewing crescent Moon phases and for smaller-aperture telescopes, for which less dimming is required.When the Moon is in its crescent phase, it does not produce as much glare as when it is full or waxing, but filtration is still recommended to achieve optimal view quality. When looking at the Moon in relatively small (60mm-80mm) telescopes, the brightness is not as distracting as in larger telescopes, but some filtration is required to get the best observations. To improve contrast and tone down glare easily in these situations, we recommend using a neutral-density 1.25" Orion 25% Transmission Moon Filter. This inexpensive accessory threads directly into a 1.25" eyepiece barrel and blocks 75% of the light gathered by the telescope. Once installed on a 1.25" telescope eyepiece, the Orion 25% Transmission Moon Filter will bring out considerably more lunar surface details thanks to the boosted contrast. Not only will more surface features and details pop out, but you can study them in greater comfort, thanks to Moon Filter reducing overall brightness without altering color. This neutral-density telescope eyepiece filter reduces irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator. Using a Moon filter also helps conserve dark-adapted vision while viewing the lunar surface.This super-small monocular is so compact and portable, you'll want to take it everywhere you go.

With 20mm eye relief and a wide, 72-deg field of view, the 8mm Delos will be a welcome addition to any amateur astronomer's gear collection. The TeleVue Delos eyepiece design was conceived as a narrower field alternative to Ethos eyepieces. Reducing the field to 72-deg allowed freedome to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. The Delos design achieves full field sharpness, virtually perfect theta distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multi-coatings and anti-reflection surfaces throughout the eyepiece. Contrast is further enhanced with a new continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, they prevent stray light from reflecting off the first surface and prevent extraneous light from entering your eye to pay off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observers preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Tele Vue Dioptrix users.Go to a star party and sidle up to any guy or gal who's got a serious telescope.

Views through the diagonal appear right-side-up and correct left-to-right, making it ideal for for daytime use with a high-power Maksutov-Cassegrain or versatile refractor telescope. Not recommended for use with Newtonian reflector telescopes.These Powermates are a better choice for 2" diagonals than Barlows, since they are nearly Parfocal. They are threaded for 48mm filters and their performance is excellent with every 1.25" and 2" eyepiece we make (yes, even the 31mm Nagler Type 5!). Both the 2" eyepiece holder and the special 2" flat top adapter use our brass clamp rings for secure operation. And, it also has a very unique feature: you can unscrew the 2" eyepiece housing and screw on a speical T-ring adapter for solid, compact attachment of CCD or camera equipment. Excellent with long eye-relief, 2" eyepieces. Using the 4x model, imagine the quality of a 35mm Panoptic at 8.8mm with 25mm of eye relief! The Powermate is NOT a Barlow so the Panoptic-Barlow Interface is not needed! The 2" Powermate fits all the way into 2" Star Diagonals, reqiring miminal refocus compared to a 2" Barlow.Edge-On Planetary eyepieces bring flat-field performance to solar system viewing in the form of three high-magnification focal lengths. Each employs a sophisticated 7-element lens design reminiscent of exotic, high-priced oculars to provide a sharp focus all the way to the edge of their wide 55-degree apparent field of view. The barrel distortion and field curvature aberrations common in standard eyepiece designs are virtually gone. Edge-On Planetary eyepieces let you push the power, whether you're canvassing the lunar terminator or studying the Jovian cloud belts. The 7-element optics are fully multi-coated for high light transmission, and each eyepiece has 20mm eye relief for viewing comfort. Other nice touches: blackened lens edges, pop-down rubber eyeguards, and barrels threaded for 1.25" filters. Barrel diameter: 1.25".Al Nagler eagerly pushed Ethos designer Paul Dellechiaie to extend the new 3.7mm focal length to reach 110-degrees, the same field as the LEM Simulator optics Al designed 45-years ago to train NASA astronauts for lunar landings (See reverse side for material on the LEM Simulator). Years after the LEM program, the memory of the 110-degree view of the simulated lunar surface moving through the triangular cabin window of the LEM inspired Al to develop an Ultra Wide Angle (his patent title) telescope eyepiece to approach that "simulator experience." When the 82-degree Nagler eyepiece hit the observing fields, it changed how amateur astronomers viewed the heavens. An early customer dubbed it a "spacewalk" view. Essentially, "the experience" is about creating an image as natural as one sees with the unaided eye. With Paul's help, Al's initial dream for amateur astronomers is now fully realized. The 3.7mm Ethos-SX is designed and crafted to combine its exceedingly wide field of view with all the contrast, color-rendition, distortion correction and center-to-edge sharpness needed to achieve that natural view. Beyond the desire to simply achieve 110-degrees, the extended field of view gave Tele Vue the ability to produce a superb planetary eyepiece with a deep sky true field of view that logically fits within the rest of the Ethos eyepiece line. With 110-degrees, the Ethos-SX has 21-percent more AFOV area than the 100-degree Ethos design.Our new Orion 0.8x Focal Reducer for Refractors increases the field of view of any astrophotography refractor telescope equipped with a 2" focuser. It also decreases the effective focal length of your imaging refractor by a factor of 0.8x, making your telescope more optically fast so it can capture bright, vivid astrophotos in less time. Using the Orion 0.8x Focal Redcucer for Refractors not only enables your astrohphotography refractor to acquire a larger field of view, but also makes it capable of capturing bright, vividly detailed astrophotos in considerable less time. With fully multi-coated, 38mm clear aperture optics housed in a sleek, all-machined, anodized aluminum body, the Orion 0.8x Focal Reducer is an affordable way to increase your astrophotography efficiency.The Delos was conceived as a narrower field Ethos. Reducing the field to 72-deg allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large.

This limited edition XT8 also includes our popular Shorty 2x Barlow lens which doubles the power of any 1.25" eyepiece, including the 25mm Sirius Plossl that comes with the scope to provide 96x magnification views. When used by itself, the included 25mm telescope eyepiece provides 48x power for medium-magnification views.The Orion SkyQuest XT6 PLUS Dobsonian features cool design enhancements and an expanded accessory package compared to our standard XT6 Classic Dob. Starting from the bottom up, we gave the SkyQuest XT6 PLUS a redesigned, streamlined Dobsonian base with weight-saving cutouts. A white trim band around the base enhances visibility in the dark. An eyepiece rack is included to hold as many as three 1.25" eyepieces. An altitude axis tensioning knob improves control of the telescope's altitude motion. The optical tube, which sports an attractive "twilight blue" metallic finish, houses a 150mm parabolic mirror with enhanced-reflectivity (94%) aluminum coatings for superior light transmission compared to standard mirrors. The included 10mm Sirius Plossl eyepiece provides powerful 120x views, or you can insert the 10mm ocular into the included Shorty 2x Barlow to boost magnification way up to a whopping 240x! The included 25mm Sirius Plossl eyepiece is great for wider-angle views at 48x, or use it with the Shorty 2x Barlow to view at 96x. We replaced the typical secondary mirror collimation setscrews with big thumbscrews, for easier, tool-free adjustment when a collimation tweak is needed. Plus, we've added an Orion Safety Film Solar Filter for viewing the Sun's ever-changing sunspots during the day! With sharp, powerful optics and point-and-view simplicity, this eye-catching 6" Dobsonian reflector shines as a plus-sized value.The SpaceProbe 130ST EQ is a rich-field Newtonian reflector with a tube only 24" long compared to the 33" tube length of the standard 130 EQ. The focal length of the ST's 130mm (5.1") primary mirror is 650mm (f/5), producing a wider field of view and brighter images for a given eyepiece focal length. The diffraction-limited parabolic primary mirror is the same type used on much larger reflectors costing substantially more. On a short-focal-length design like this one, a parabolic mirror is a must for delivering sharp, detailed images. This scope package includes an EQ-2 equatorial mount with dual setting circles and manual slow-motion controls, adjustable aluminum tripod with accessory tray, two Plossl eyepieces (25mm and 10mm), and a 6x30 achromatic finder scope. One-year limited warranty.Eyeglass wearers love our UltraView series of binoculars not only for their 22mm eye relief but also their great light-gathering capabilities and superb optics.

Your first scan of the Milky Way will prove it - pinpoint stars set in bold contrast against the dark background. Gorgeous! The extra-large BAK-4 prisms and advanced multi-coatings on all optical surfaces really drink in the light. The eyepieces focus individually, which yields a sturdier mechanical design than a center-focus mechanism. And with 23mm of eye relief, even eyeglass wearers will see the full field of view. Supple rubber eyecups can fold down, if desired, for more comfortable use while wearing eyeglasses. This Resolux 10.5x70 binocular' s all-metal housing is armored with thick rubber to ensure a secure, comfortable grip. Each binocular comes with lens caps, heavy-duty tripod adapter, and neck strap.

When using a truss tube Dobsonian for solar observing, always use a Light Shroud and a properly sized solar filter. Make sure there are no gaps between the Shroud and the telescope where direct sunlight can reach the mirror, otherwise eye injury or damage to the telescope can occur. Before using any telescope for solar observing, install protective covers on all optical components. Glancing through an uncovered optical system can cause permanent eye damage. Always install protective caps on all optical instruments if left out during daylight hours.With exceptional optics, top-notch features and beautiful fit and finish, the Orion EON 115mm ED Triplet refractor telescope offers wide-field observers and astrophotographers an impeccably crafted, true-color instrument at a great price. This premium refractor telescope's generous, 115mm (4.5") aperture collects ample light from faint deep-sky objects to provide crisp images with excellent color correction by virtue of the element of FK-61 extra-low dispersion ("ED") optical glass in its air-spaced triplet objective lens. The apochromatic refractor's medium 805mm focal length gives it a fairly fast, f/7.0 f-ratio which performs exceptionally well for wide-field visual use or deep-sky astrophotography. Multilayer anti-reflection coatings on every air-to-glass lens surface maximizes light transmission; while an extendable dew shield, blackened lens edges, and multiple internal knife-edge baffles eliminate off-axis reflections and glare to ensure excellent contrast. A massive, 3" dual-speed (11:1) Crayford focuser provides precise, backlash-free focus control and easily supports heavy astrophotography gear. The EON 115mm ED's focuser can be rotated in two places, allowing camera framing to be set independently from your preferred positioning of the telescope focus knobs. Not only is the EON 115mm ED Refractor a great wide-field performer, it's also conveniently compact and measures just 27.75" with its sliding dew shield retracted for easy transport and storage in the included 30.5" long foam-lined hard carry case. The EON 115mm refractor telescope features a dovetail finder scope base for use of optional aiming devices or Mini Guide Scopes. A thread-on metal objective lens cap, a narrow "Vixen-style" dovetail mounting bar and two heavy-duty hinged tube rings with multiple, pre-drilled and tapped M6 holes along the top and bottom are included.
