Orion SkyQuest XT8 Review | Is it a good telescope?

Orion is a huge brand that manufactures premium-quality telescopes, binoculars, various optic gear pieces, and a huge array of accessories to complement their performance. 

Their two most popular series of telescopes are the Star Blast (one of my favorite cheap reflector telescopes) and SkyQuest (Dobsonian telescopes); today we’re going to talk about one of their most recent launches – the Sky Quest XT8 Dobsonian Telescope. 

Orion Skyquest XT8 Review – At first glance

Most people who’ve used the Sky Quest XT6 loved it; it was a classic telescope outfitted with a myriad of top-quality features, but it seemed to be lacking just a little bit of ‘anything’ before we could label it as ‘perfect’. It’s pretty safe to say that XT8 picked up where XT6 left off and filled the room left for improvements. 

Orion 8945 SkyQuest XT8 Classic Dobsonian Telescope
  • Item may ship in more than one box and may arrive separately
  • A large aperture Classic Dobsonian reflector telescope at a very affordable price!
  • 8" diameter reflector optics lets you view the Moon and planets in close up detail, and has enough light grasp to pull in pleasing views of faint nebulas, galaxies and star clusters
  • A perfect Dobsonian telescope that can last a lifetime for the beginning astronomy enthusiast or whole family
  • The ultra-stable Dobsonian base keeps the reflector optical tube perfectly balanced for point-and-view ease of use

In terms of aesthetics, Orion’s SkyQuest XT8 looks exactly like its predecessor; it features a Dobsonian Reflector design and a large 8-inch aperture (improved by 2 inches in comparison to XT6), superb 48x magnification, and it retained all the great features XT6 packs, such as 300x top theoretical magnification, long tubing, and sturdy construction.

This telescope does look pretty huge, and it’s more than safe to assume that it weighs a ton. Upon closer inspection, you’d realize that it actually weighs only 41 pounds, which isn’t terrible for a telescope of its size. Overall, there are dozens of things to like even at first glance, so why don’t we take a little bit closer look to see what it actually has to offer in terms of performance?

Manufacturer specs

Orion’s SkyQuest XT8 telescope ‘hides’ numerous state-of-the-art technologies and features that are invisible to the naked eye. It rocks a 2-inch single-speed Crayford style focuser, a Red-Dot finder for convenience, and Aluminum and Silicon Dioxide optical coatings that deliver nearly unparalleled quality of its optical elements. Here are the main specs of the XT8 telescope:

Design type: Dobsonian Telescope

Aperture: 8 inches 

Focal Length (FL): 1200 

Focal Ratio (FR): f/6

Optical Coating type: Aluminum and Silicon dioxide

Lowest magnification: 29x

Highest magnification: 300x

Finder type: Red Dot

Mount type: Standard Dobsonian Mount

OTA Length (in inches): 46.5

OTA Weight (in pounds): 20.3

Total weight (in pounds): 41

Main features

Orion’s XT8 rocks an 8-inch aperture that’s equally suited for moon watching, planet observation, and diving into (some realms) of the deep space. What’s so interesting about this type of aperture is that it complements all the other optical elements perfectly, making this telescope a very versatile one. It works just as great at ‘short’ range as it performs excellently at longer distances.

Furthermore, the mount this telescope is supplied with isn’t ‘special’ in the purest sense of the word, but its functionality is just brilliant. It offers the much needed stability to the scope and significantly reduces the need to recalibrate, re-adjust, or realign it. Apart from being balanced and stable, it’s also incredibly easy to operate. 

The robustness of the XT8 is a feature unto itself; namely, this telescope is made from the sturdiest materials that are supposed to last decades, or maybe even centuries if used and maintained correctly. 

Lastly on the note of versatility of Orion’s Sky Quest XT8, it also comes supplied with a 2-inch focuser that is compatible with most 1.25-inch or 2-inch standard telescope eyepieces, a 25-millimeter Sirius Plossl complementary eyepiece, a convenient EZ Finder reflex sight, a collimation cap, and Starry Night image processing software. 

Optics quality

Orion’s SkyQuest XT8 performs amazingly well optics-wise; its main mirror sports borosilicate glass, otherwise known as Pyrex. Its reflectivity is ‘sky high’ (literally), and it cools down significantly faster in comparison to average plate-glass mirrors. 

This telescope comes supplied with the 25-millimeter Plossl eyepiece, which works great at shorter distances; if you want to ramp up its performance, you can switch it with wide-field eyepieces (two-inch models). 

Now, what’s really interesting about this telescope is the fact that it comes equipped with a solar-safe filter. This basically means that you can gaze anywhere close or even directly at the sun without burning the mirrors up. Its finderscope is pretty great for beginners as it’s a straightforward little red dot – it’s easy to use and doesn’t require too much practice to learn how to properly use it.


Even though Orion’s SkyQuest XT8 isn’t a schoolbook example of a ‘budget’ telescope, it certainly is fairly cheap. As a matter of fact, all the features it comes supplied with are typically ‘mounted’ on significantly more expensive models. That being said, the first ‘pro’ of the XT8 is affordability. 

Secondly or better said more importantly, the quality of optics integrated into this telescope is ravishing, and that’s a major understatement. This telescope rocks a huge aperture, phenomenal magnification, advanced optical mechanics, and top-quality solar-filter. 

Moreover, apart from being supplied with state-of-the-art features, the XT8 telescope is actually very easy to operate and use. It rocks a plain red-dot focuser, and all of its features are self-explanatory, even if you’re a beginner. 


There are only a handful of things that people wish to be improved in XT8’s design. Generally speaking, this telescope needs a bit more eyepieces if you want to fully utilize its functionality. The ones that it comes supplied with are great, but they’re also somewhat limited. 

Now, even though a red-dot finder is a phenomenal feature for a beginner astrophotograper, most professionals and experienced astrologists wouldn’t say that it’s ‘versatile’ per se. Lastly, a couple more accessories wouldn’t hurt – most similarly priced Dobsonian telescopes pack at least 5-6 gratis goodies. 


All Orion-made gear is well worth the buck, but is SkyQuest XT8 a right choice for you? With phenomenal optics and portability, as well as with large aperture and a balanced mount, most veterans would give it a shot. On the flip side, it rocks all the features a beginner needs to embark on an unforgettable journey of star-gazing and space observation. 

It has its ups and downs, and it certainly isn’t ‘perfect’ true to form, but it’s a highly valuable Dobsonian telescope that is worth every cent.
