Orion SkyQuest XT8 PLUS Dobsonian Reflector Telescope
What do you do with a best-selling, fan-favorite telescope that has developed a dedicated following among amateur astronomers the world over? Here at Orion, we gave our popular XT8 Classic Dobsonian a serious makeover! Using the XT8 Classic as a starting point, we added top-notch features and accessories to create the Orion SkyQuest XT8 PLUS Dobsonian Reflector. This deluxe upgrade of our stalwart 8″ reflector telescope boasts a redesigned Dobsonian base, adjustable altitude axis tension, a 2″ dual-speed Crayford focuser, and a host of other upgraded features and included accessories to enhance your observing experience.
The sleek redesigned base of our SkyQuest XT8 PLUS Dobsonian not only looks great, it also features weight-reducing cutouts which help make the XT8 PLUS more portable than its XT8 Classic counterpart. The base is quite visible, even in the dark of night, thanks to its white trim. Topping the base (literally) is the big, 8″-aperture, f/5.9 reflector telescope optical tube with a unique, eye-catching metallic blue color. The XT8 PLUS features adjustable tension knobs on the altitude axis, which replace the tensioning springs found on the XT8 Classic model. These adjustable knobs make the XT8 PLUS more versatile, since you can now adjust the tension of the altitude axis of motion to allow use of heavier 2″ eyepieces, Barlow lenses, multiple finder scopes, and other hefty accessories. With the altitude tension properly adjusted, using heavier accessories will not cause the optical tube to drift downwards during use.
The SkyQuest XT8 PLUS Dobsonian is built around an 8″ (203mm) diameter parabolic primary mirror mounted in a sturdy, 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. The Moon and planets of our solar system like Jupiter, Saturn, and Mars shine brightly in the Orion SkyQuest XT8 PLUS, allowing you to inspect them in high-resolution detail. Enhanced-reflectivity mirror coatings boost the XT8 PLUS Dobsonian’s mirror up to 94% reflectivity so as much light as possible is transmitted to the eyepiece, resulting in exceptionally bright, clear views. The point-and-view simplicity of the Dobsonian design is not as complicated as a telescope attached to an equatorial (EQ) mount and tripod. With a little practice, your whole family can use the XT8 PLUS Dobsonian telescope to scan the heavens just like experienced astronomers.
We’ve equipped the XT8 PLUS with a thorough set of top-notch accessories to enrich your stargazing experiences.
Fine-tune focus for peak performance with the dual-speed Crayford focuser
The big, 2″ dual-speed Crayford focuser of the XT8 PLUS is a significant upgrade compared to the single-speed model on the XT8 Classic. A step-down 1.25″ adapter is included to allow use of both 1.25″ and 2″ eyepieces. Thanks to the Crayford design, focus adjustments are smooth, accurate, and virtually free of backlash and flexure. With an 11:1 fine-focus ratio, you’ll be able to make precise adjustments for sharp, crisply detailed views.
View at a variety of magnifications with two included eyepieces and a Shorty 2x Barlow
The big, 2″ 28mm DeepView eyepiece will help you obtain expansive 42x views, while the included 1.25″ 10mm Sirius Plossl ocular will provide close-up, 120-power observations. For even more powerful views, use the included 1.25″ Shorty 2x Barlow lens to double the power of any 1.25″ eyepiece. You can use the Shorty 2x Barlow with the 10mm Sirius Plossl eyepiece to achieve a very powerful, 240x view.
Convenient thumbscrew-equipped secondary mirror cell makes adjustments easy
Like all reflector telescopes, the XT8 PLUS will likely require minor periodic maintenance to make sure its optical mirrors are aligned, or “collimated”. To make collimation adjustments nice and easy, we’ve outfitted the XT8 PLUS Dobsonian telescope’s secondary mirror with knurled thumbscrews so you don’t have to hassle with tools to align the reflecting optics of the telescope.
Bright white base trim helps avoid accidents in dark conditions
Since stargazing is best when it is very dark outside, there is always a chance of accidentally bumping into or tripping over pieces of equipment that are hard to see in low-light conditions. To help avoid such mishaps from ruining your next observing session, we’ve made the base of the XT8 PLUS easy to see, even in the dark of night, thanks to its highly visible white trim.
You can keep one 2″ eyepiece and up to three 1.25″ eyepieces at-the-ready with the included eyepiece rack. It’s easy to aim the XT8 PLUS easily and accurately with the included Orion EZ Finder II reflex sight. Also included are a quick collimation cap, and dust caps for the reflector telescope tube and focuser.
