![]() The XT8i has an aperture of 203mm, a focal length of 1200mm resulting in a focal ratio of f/5.9. What Do The Orion SkyQuest XT8i IntelliScope’s Specifications Mean? Spherical optics suffer from spherical aberration resulting in a lack of focus and clarity (this shouldn’t be an issue for the XT8i as it uses a parabolic mirror).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 aberration.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). ![]() Thankfully even out of the box the XT8i appears to come collimated so this shouldn’t be too much of an issue when you’re immediately starting out.Īnyways, regarding the pros of the reflector optics inside the the XT8i, they include the following : Of course the crisper more detailed image will only be possible when aligned properly. This in turn will allow for the images being viewed to align at a singular point resulting in crisper viewing experience. The XT8i in this case comes with Newtonian reflector optics inside the tube meaning the primary mirror inside is a parabolic one. Just so you know, telescopes tend to come in one of 3 different optical variants, these being reflector, refractor and compound optics. The IntelliScope simply provides the use of a more advanced manual computerised mount (which I’ll get into later in the review) which of course explains the XT8i’s price hike over the XT8 for example. The SkyQuest XT line up of telescopes offered by Orion all provide the same type of optics within their devices with the main differences being the computerised element of the devices.
