9/17/2023 0 Comments Orion sky quest xt8![]() ![]() ![]() The SkyQuest has some very solid specs with an aperture of 203mm, a focal length of 1200mm resulting in a focal ratio of f/5.9. What Do The Orion SkyQuest XT8 Classic Dobsonian’s Specifications Mean? If you want a visual guidance on how to collimate the SkyQuest XT8, I’d highly suggest watching the video below. The optics within the SkyQuest XT8 are very solid for the price bracket it falls within (roughly $350 – $400) and besides the minor annoyances of having to collimate and maintain the system regularly, there aren’t anything bad about the optics that stands out. Can’t view things on earth very well unlike the other 2 variations.Low focal ratio reflector devices tend to suffer a lot more from comatic aberration.You’ll regularly need to collimate the device too as they’re easy to knock out of alignment.The optics are exposed meaning you’d need to clean them up regularly.These optics don’t suffer from chromatic aberrationĪs for the cons of the reflector optics, they include the following :.Reflectors are generally cheaper to manufacture, resulting in cheaper telescopes.Great for viewings faint objects in the sky as all types of light can pass through the lenses (this isn’t the case for a refractor).The mirror is also made of a higher quality glass called borosilicate glass AKA Pyrex, which basically means the optics cool down faster.īesides this pro, the other pros of the SkyQuest XT8, again similar to the XT6, include the following : I won’t really be going into much detail regarding the other variation in this review but, the reason they’ve been mentioned is to compare the pros and cons of reflector optics to themįirstly, you should know that the XT8 uses a Newtonian reflector optics which is a parabolic mirror and not a spherical one meaning it won’t suffer from spherical aberration that a cheaper reflector would suffer from. If you’re unfamiliar with the different optics found within telescope, I’m sure you’ll be surprised to know that besides reflector optics, telescopes also tend to use 2 other optical variations, namely refractor and compound based optics. The SkyQuest XT8 is simply the bigger brother to the other highly recommended telescope in the SkyQuest XT6 and much like the XT6 the XT8 also uses reflector based optics to contribute to your visual experience with the system. ![]() $649.99 Check Price On Amazon Click Here For Orion’s Official Pricing!
