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.
The big, 2" dual-speed Crayford focuser installed on the XT8 PLUS is a significant upgrade compared to the single-speed focuser of the XT8 Classic. The focuser features a step-down 1.25" adapter so you can use both powerful 1.25" eyepieces and wide-field 2" oculars. Thanks to its Crayford design, focus adjustments are smooth, accurate, and virtually free of backlash and flexure, even with heavier 2" accessories installed. With an 11:1 fine-focus ratio, you'll be able to make extremely precise adjustments for sharp, crisply detailed views of whatever celestial quarry you turn your XT8 PLUS towards.
We've equipped the XT8 PLUS with a thorough set of top-notch accessories to enrich your stargazing experiences. This is one telescope you'll be able to use during daytime hours, thanks to the included Safety Film Solar Filter, which lets you safely observe sunspots as they march across the surface of our nearest star. A 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 Shorty 2x Barlow lens to double the power of any 1.25" telescope eyepiece. You can keep one 2" eyepiece and up to three 1.25" eyepieces at-the-ready with the included eyepiece rack. Aim the XT8 PLUS easily and accurately with the included Orion EZ Finder II reflex sight. Also included are a quick collimation cap for mirror alignment, dust caps for the reflector telescope tube and focuser, and special edition of Starry Night astronomy software with a SkyTheater DVD - a $69.90 value!
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.
For easy transport and storage, the Orion XT8 PLUS telescope can conveniently be broken-down into two separate pieces. By unthreading the two altitude tension knobs from the Dobsonian base, you can detach the 46.5" long reflector optical tube and transport each piece separately. With an assembled weight of 42 lbs., the XT8 PLUS is a lot of telescope offered at an amazingly affordable price.

Featuring a 102mm, f/6.5 achromatic objective lens and a GoTo database of over 4,000 objects, the Orion StarSeeker II 102mm GoTo Refractor Telescope is capable of showing you and your family spectacular views of celestial curiosities on any clear night. Thanks to its straightforward SkyAlign alignment technology, motorized mount, and computerized GoTo system, the StarSeeker II 102mm GoTo Refractor is easy for anyone to use - no matter how familiar or unfamiliar you may be with the night sky.
Using SkyAlign to align the StarSeeker's computerized GoTo system is delightfully easy. All you have to do is enter basic information into the hand controller like the date, time, and your location. Then use the hand controller buttons to point the telescope to any three bright stars in the sky. Unlike many other GoTo systems, SkyAlign does not require you to enter the names of the stars used for alignment, so you don't have to hassle with star charts to determine a star name. This makes it nice and easy for anyone to align the telescope in minutes - even if you do not know the name of a single star in the sky.
Once the easy alignment process is completed, the computerized GoTo system can locate and point the attached refractor telescope to more than 4,000 celestial objects with a few button pushes on the illuminated handheld controller. You'll be able to find fascinating objects to view on every clear night! Once an object is located, the StarSeeker II will automatically track the object's apparent motion across the sky and keep it centered in the telescope eyepiece so you can enjoy the view for as long as you wish until you move on the next object. Beginners will especially appreciate the built-in Sky Tour feature, which commands the StarSeeker II 102mm to find the most interesting objects in the sky and automatically aims the telescope at each one. Both experienced astronomers and "newbies" will have fun exploring the comprehensive database of over 4,000 celestial objects, which includes the planets, Moon, and customized lists of all the best deep-sky objects, bright double-stars, and variable stars to observe. Regardless of your previous astronomy experience, the Orion StarSeeker 102mm GoTo Refractor Telescope will turn you into an instant astronomer!
