It is that images appear brighter in XT8, and also sharper at high magnification. So using the same eyepiece, both telescopes will provide the same magnification and field of view. It’s the focal length that dictates the field of view. Regarding the optics, due to the differences in the focal ratio of both the XT6 and XT8, they have the same focal length. With any optical instrument, whether it is a telescope or a pair of binoculars, this is the one major thing that dictates its overall power and what you will ultimately be able to see. The Orion SkyQuest XT6 and XT8 differentiate in one main way – the XT8 has an 8″ (203mm) diameter parabolic primary mirror compared to a 6″ (15mm) diameter parabolic primary mirror, meaning they provide different light-gathering abilities. If you are low on funds, the XT6 plus, is your next best bet:Ĭheck Price On Amazon Choosing Between The Orion SkyQuest XT6 and XT8 Still, if you have the budget, then the XT8 Plus is going to be your ultimate, best buy. Again, they are more expensive than their classic alternatives. Now the plusses are again an upgrade still. There are two variations of each XT model: However, it isn’t without cost – it is more expensive. It works far better under dark or even reasonably dark skies and you get a range of extra additional accessories included too. Nevertheless, it is the XT8 that comes out on top. So as well as being able to observe the Moon and planets of our solar system you get a dramatic increase in the ability to observe DSO’s (Deep Sky Objects).īoth the XT6 and XT8 are easy to use, portable, point and view Dobsonian Telescopes that provide a lot of power for their respective prices.īeing built around parabolic mirrors ensures excellent light-gathering, and the stable base included on both variants provides vibration-free images even when viewing at high power. The XT8 is optically superior to the XT6 variant, collecting 78% more light and utilizing enhanced-reflectivity mirror coatings. So, what is better, the Orion SkyQuest XT6 vs XT8? Most astronomers agree that the XT8 is better in most circumstances than the XT6. Today, I’ll be walking you through the key similarities and differences between both variants, enabling you to select the one that suits your own needs, preferences, and budget. Not sure what is best for you? Well, you’ve come to the right place. A good example is Foxconn, which makes most of the electronics we use.Looking at the Orion SkyQuest XT6 and XT8. This is is because they might be fabricated on different lines or have to pass different quality criteria (to justify one being more expensive, which in this case doesn't seem to be the case). Note, however, that different brands could be made in the same factory and still be of different quality. Given that they basically cost the same, I suspect the quality is the same. So, yes, the scopes are made in the same factory but you should still check out the differences between them because they come with different stuff as standard and perhaps one of the suppliers has better support than the other. They could save money elsewhere, such as supplying the scope with only one eyepiece (everyone upgrades the cheapo eyepieces anyway). I can understand why they're cutting corners to hit price targets, but the bearings aren't the thing to skimp on. It's not like good bearings are a secret: the concept of the Dobsonian mount is founded on cheap but silky smooth motions. It's actually rather frustrating that these companies don't get the bearings right. Thankfully, a cheap mod (gluing laminate to the underside of the rocker) will fix the motion. The XT and smaller XX scopes skip the Ebonystar laminate and the result is bad static friction and nasty motions. I had the XX12i and that had Teflon/Ebonystar, which was adequate. In my experience, the main problem is the crappy bearings they supply on their smaller scopes. Here is a post comparing the quality of Synta and GSO scopes:
