Our take on the Celestron 800 XLT Schmidt-Cassegrain Telescope

The Celestron 800 XLT is an 8-inch Schmidt-Cassegrain optical tube with Celestron's XLT multicoatings, sold as the tube itself rather than a full computerized kit. The 203 mm aperture gathers enough light for galaxies, globular clusters and planetary detail, and the folded SCT design keeps the tube short and light enough for most mid-size mounts. It suits observers who already own a GoTo mount or want to build one around a capable 8-inch tube. Against 8-inch Dobsonians it trades some light grasp and simplicity for a compact, mount-friendly tube; against smaller refractors it wins clearly on deep-sky reach.

Best forDeep-sky observers wanting an 8-inch tubeOwners of a GoTo or German equatorial mountPlanetary and lunar viewing with high powerAstrophotographers building a compact SCT rig
Pros
  • 203 mm aperture shows faint galaxies and resolves globular clusters
  • Compact folded tube is far easier to mount and store than an 8-inch Dobsonian
  • XLT coatings improve light transmission over standard coatings
  • Accepts 2-inch and 1.25-inch eyepieces and standard SCT accessories
  • Long focal length gives high magnification with modest eyepieces
Cons
  • Heavy at about 42 lb once mounted, so a sturdy mount is mandatory
  • Narrow field of view makes it poor for wide star fields
  • Needs collimation and cool-down time to perform at its best
  • Tube-only configuration means mount and tripod are extra

What reviewers say

Owners rate the 8-inch SCT optics highly for lunar, planetary and brighter deep-sky targets, and praise the compact tube. Most criticism centers on weight, the narrow field and the need for a solid mount.

What people mention
  • Optical qualityPraisedOwners report crisp lunar and planetary detail and good contrast on bright deep-sky objects.
  • WeightCriticisedThe tube and mount together are heavy, and reviewers say a flimsy tripod ruins the experience.
  • Field of viewCriticisedThe long focal length gives a narrow view, so large nebulae and star fields are hard to frame.
  • CollimationMixedSome find collimation straightforward, while others say it needs checking often after transport.
  • BuildPraisedBuyers describe the tube as solid and the focuser as smooth for the class.

Questions and answers

Is this a complete telescope or just the tube?
It is the optical tube assembly. A mount, tripod and eyepieces are separate, so budget for a sturdy GoTo or equatorial mount.
What can I see with an 8-inch Schmidt-Cassegrain?
Lunar craters, Saturn's rings, Jupiter's bands, globular clusters, brighter nebulae and many galaxies. Faint objects need dark skies.
How does it compare with an 8-inch Dobsonian?
The Dobsonian gives a wider field and simpler setup for less outlay. The SCT is more compact, easier to mount and better for tracking and photography.
Do I need to collimate it?
Yes, occasionally. Schmidt-Cassegrains hold collimation well but should be checked after rough transport, and the process is quick with a star test.
Can I use it for astrophotography?
Yes, especially for planets and small galaxies. Its long focal length and slow focal ratio make it less suited to wide-field imaging.
What eyepieces fit?
It uses standard SCT threads and accepts both 1.25-inch and 2-inch eyepieces and diagonals with the right adapter.
Where is the Celestron 800 XLT Schmidt-Cassegrain Telescope cheapest?
At Adorama, for $2,899.00, as of our latest check.
Where can I buy the Celestron 800 XLT Schmidt-Cassegrain Telescope?
