Celebrate with the stars this holiday season with a Limited Edition SkyQuest XT8 Classic Dobsonian!

This special version of our best-selling 8” Classic Dobsonian reflector telescope is not only a gorgeous ruby-red color, it’s also outfitted with two awesome accessories to enhance each viewing experience. An included 35mm Orion DeepView 2” eyepiece lets you take advantage of the XT8’s smooth-adjusting 2” Crayford focuser and enjoy wide, 56° views of 34x power through the telescope. 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.

Classic Dob Chart

The Limited Edition SkyQuest XT8 Classic Dobsonian is built around an 8" (203mm) diameter parabolic primary mirror mounted in a cast-aluminum support cell. The mirror collects 78% more light than a 6" mirror, so you get a significant increase in ability to observe dust lanes in nebulas, resolve the cores of prominent globular star clusters, and to reveal some of the more subtle structures in faint galaxies. The 1200mm focal length (f/5.9) XT8 mirror allows you to obtain clear and crisp views at moderate to high magnifications on clear nights with good seeing conditions. Enhanced-reflectivity mirror coatings boost the XT8 Classic Dobsonian’s mirror to 94% reflectivity so as much light as possible is transmitted to the eyepiece, for clear and bright views.

The Dobsonian base of the XT8 Classic provides a simple and stable low-profile altazimuth platform for the 8" aperture reflector optical tube. The tube attaches securely to the base by virtue of Orion’s CorrecTension Friction Optimization system, which utilizes heavy-duty springs to both securely couple the tube to the base, and to keep the telescope in constant balance to avoid drifting during observations. Even with large 2" eyepieces and accessories installed, the XT8 Dobsonian telescope optical tube will remain balanced throughout your viewing sessions.

The Limited Edition SkyQuest XT8 Classic Dobsonian features a 2" Crayford focuser that accepts both 1.25" and 2" accessories. Focus adjustments are smooth, accurate, and virtually free of backlash and flexure, even with heavier 2" accessories installed.

An included Orion EZ Finder II reflex sight allows you to easily and accurately aim the 8" Classic Dobsonian. Also included are a quick collimation cap for easy mirror alignment, dust caps for the reflector telescope tube and focuser, and a special edition of Starry Night astronomy software and a SkyTheater DVD - a $69.90 value!

The Orion Limited Edition XT8 Classic Dobsonian telescope can conveniently be separated into two pieces for easy transport and storage. By unhooking the two CorrecTension springs from the Dobsonian base you can detach the 46.5" long optical tube. The Limited Edition XT8 reflector optical tube weighs 20.3 lbs., while the 19" diameter Dobsonian base tips the scales at 20.7 lbs. With an assembled weight of 41 lbs., the XT8 Classic Dobsonian can be easily moved to and from your favorite observing site, whether it’s just a few steps out the back door, or many miles down the road.

A great telescope with the optical strength to please serious beginners and veteran skygazers alike, the Orion Limited Edition SkyQuest XT8 Classic Dobsonian reflector will provide years of astronomical adventure for you and your whole family. The value-packed Limited Edition XT8 Classic is an ideal gift for any astronomer on your list. Order now before this truly limited edition Dobsonian reflector telescope sells out!

User level

User level

Beginner - Suited for a wide range of uses, Level 1 telescopes are simple to operate and set up. Some initial assembly may be required. Very good optical and mechanical quality. Great for families, young people, and folks who don't want to mess with equipment but just want to take a look. Any of these scopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulas! Referring to the manual is recommended.

Intermediate - These scopes offer higher performance and more advanced features than Level 1 models. They typically take a bit longer to learn and need some set-up or adjustments. But anyone with the slightest technical bent will have no problem getting familiar with these models. Referring to the manual is recommended.

Advanced - These scopes provide the best performance but may require more skill to master and appreciate. They have exceptionally fine optics and mechanics. Some are easy to use but are but on the large or heavy side. Some are intended for specialized uses. These scopes will appeal to the more technically inclined. Referring to the manual is highly recommended.

Expert - Expert telescopes offer uncompromising optical and mechanical quality for the most demanding amateur astronomer. They may be technically involved or designed for specialized use, such as astrophotography or detailed deep sky observation. They carry a premium price, but are designed to provide the ultimate performance in the field. Referring to the manual is highly recommended.

Optical design

Optical design

Reflector telescopes use a pair of large and small mirrors to direct incoming light to the eyepiece. Refractor telescopes refract, or "bend" incoming light to a focus by means of an objective lens. Cassegrain telescopes, such as Maksutov-Cassegrains, "fold" incoming light using two mirrors and a front "corrector" lens.

Reflector
Optical diameter

Optical diameter

The optical diameter (also known as aperture), is the size of the telescope's main light collecting lens or mirror, measured in millimeters or inches. As the diameter increases, more light is collected and the resolution increases.

203mm
Focal length

Focal length

The focal ratio of an optical system is the ratio of a telescope's focal length to its aperture. Short focal ratios (f/5, f/4.5) produce wide fields of view and small image scales, while long focal lengths produce narrower fields of views and larger image scales.

Focal ratio

Focal ratio

The focal ratio of an optical system is the ratio of a telescope's focal length to its aperture. Short focal ratios (f/5, f/4.5) produce wide fields of view and small image scales, while long focal lengths produce narrower fields of views and larger image scales.

f/5.9
Optics type

Optics type

Newtonian reflectors will have either a spherical shaped mirror, which is less expensive to produce, or a higher quality parabola, which does not result in spherical aberration. Cassegrain telescopes routinely use spheres in addition to other lenses in the optical path to correct for residual spherical aberration. Refractors use a series of lenses to provide a clear image. Designs range from a standard air-spaced doublet (two lenses in a row) to exotic designs such as oil-spaced triplets and 4-element multi group lenses.

Parabolic
Glass material

Glass material

Refractors use glass lenses to focus the light, and the glass material plays an important role in the quality of the resulting image. Standard achromatic refractors routinely use Crown and Flint for the two elements, but more expensive apochromatic refractors can use ED (extra low dispersion) glass for one or more of the lenses. Reflector mirrors are made from glass with different levels of thermal expansion. Standard mirrors are made from material such as Soda-Lime Plate glass and BK-7 glass. Glass with Pyrex or other low thermal expansion material will not change shape as dramatically during the cool-down period, resulting in more stable images during this period.

Resolving power

Resolving power

The theoretical resolving power of a telescope can be calculated with the following formula: Resolving power (in arc seconds) = 4.56 divided by aperture of telescope (in inches). In metric units, this is: Resolving power (in arc seconds) = 116 divided by aperture of telescope (in millimeters). Note that the formula is independent of the telescope type or model, and is based only upon the aperture of the telescope. So the larger the telescope's aperture, the more it is capable of resolving. This is important to keep in mind when observing astronomical objects which require high resolution for best viewing, such as planets and double stars. However, it is usually atmospheric seeing conditions (not the telescope) which limits the actual resolving power on a given night; rarely is resolution less than one arc-second possible from even the best viewing locations on Earth.

0.57arc*sec
Lowest useful magnification

Lowest useful magnification

Lowest useful magnification is the power at which the exit pupil becomes 7mm in diameter. Powers below this can still be reached with the telescope to give wider fields of view, but the image no longer becomes brighter at a lower power. This is due to the fact that the exit pupil of the telescope (the beam of light exiting the eyepiece) is now larger than the average person's dark adapted pupil, and no more light can fit into the eye.

29x
Highest useful magnification

Highest useful magnification

The highest practical limit is different from the often used "highest theoretical magnification" specification. The "theoretical" limit generally is 50x the aperture of the scope in inches (2x the aperture in mm). So for example, an 80mm refractor is capable of 160x, and a 10" telescope is theoretically capable of 500x magnification. But after approximately 300x, theory breaks down and real world problems take over. The atmosphere above us is constantly in motion, and it will distort the image seen through the telescope. This effect may not be noticeable at lower powers, but at higher powers the atmosphere will dramatically blur the object, reducing the quality of the image. On a good night (a night where the air above is steady and the stars aren't twinkling), the practical upper limit of a large telescope is 300x, even thought the theoretical limit may be much higher. This doesn't mean the scope will never be able to reach those higher "theoretical" powers - there will be that rare night where the atmosphere is perfectly still and the scope can be pushed past it's practical limit, but those nights will be few and far between.

The limiting stellar magnitude is a measure of the faintest star you can see through the telescope.
