    The 8mm Delos eyepiece from Tele Vue is great for obtaining sharp and clear views with moderate magnification. 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. Take a peek in their accessory case and you're almost certain to spot one or more Panoptics. That's because Panoptics set the standard for performance in wide-field eyepieces. They feature a six-element, four-group optical design that renders sharp, high-contrast images agross a 68-deg apparent field, with excellent color correction. Of course, the optics are fully multi-coated and are contained in a housing of exquisite craftmanship. Panoptics will repay the investment you make in them many times over with spectacular views at medium to low power.

    Looking through a Nagler eyepiece is like taking a spacewalk. That's because the 82-deg apparent field of view seems almost boundless: you have to move your eye around to take in the entire scene. The exquisite sharpness, contrast, and comfort , in addition to the monster apparent field of view, make Naglers the eyepieces of choice for advanced amateur and professional astronomers. Nagler eyepieces belong in the equipment arsenal of every serious planetary and deep-sky observer.
    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.
    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.
    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. With Ethos performance standards as benchmarks, 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.

    Whiter and brighter images. Simply put, that is the benefit the Everbrite mirror coating. This exotic, dielectric, nonmetallic coating is 99% reflective across the full visual spectrum, resulting in the whitest, most natural image available. The coating is painstakingly applied to Pyrex with a surface accuracy of a 1/10 wave flatness. In addition to higher reflectivity than a conventional aluminum or silver coated diagonal, the Everbrite coatings also provide higher contrast and resolution during critical planetary, lunar, and binary star observations. This is an absolutely premium 2" star diagonal that will give you all the visual performance your scope is capable of delivering. It's a worthy upgrade for virtually any Schmidt-Cassegrain, Maksutov-Cassegrain, or refractor that uses a 2" star diagonal.
    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.

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.
    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.
    Effectively cleans filmy residue at the microscopic level. Increases resolution and light transmission, restoring optics to their original performance level. Will not damage optical coatings. Also reduces dew formation.
