The popularity of Celestron's previous short tube refractor models inspired them to go a step further with the introduction of a 102mm aperture model and have it paired with their highly popular and well regarded SLT range of mounts. You'll find that astronomical viewing is a delight with this 102mm/4" aperture telescope, which offers a 63% increase in image brightness over smaller 80mm aperture scopes.

This short-tube telescope with a fast f/6.5 optical system gives images that are bright and crisp. With its wide 1.7° field of view, the NexStar 102 SLT is optimal for scanning large areas of the sky and is ideal for viewing a wide range of astronomical objects.  Although the telescope makes a wonderful entry to mid-level astronomical scope, with the use of an optional erect image diagonal, the 102SLT also makes a superb terrestrial (land) viewing telescope too.

The 102SLT, like the other models in Celestron's SLT Series, comes with a fully computerised hand control with a database of over 4,000 celestial objects! With its pre-assembled, adjustable steel tripod, the NexStar 102SLT can be up and ready to use in a matter of minutes. Celestron's SkyAlign alignment technology, and the included StarPointer Finderscope with a red LED, makes aligning a breeze.

See the video below on how easy it is to set the SLT telescopes up ready for a night under the stars!
