Designed to be an affordable entry level to mid-level computerized GoTo telescope, the NexStar SLT refractors, reflectors, and Maks are available in the most popular sizes and are loaded with valuable design features. With preassembled, adjustable stainless steel tripods, and quick release fork arms and tubes, NexStar SLT telescopes can be set up in a matter of minutes – with no tools required! You can see details of the lunar surface, Venus and its phases, polar caps on Mars, Jupiter and its four moons, Saturn with its rings plainly visible and much more!
Intelligent Design
The internal battery compartment provides power to the high precision servo motors for rigid low-vibration performance while eliminating cord wrap issues associated with external battery packs.
With the NexStar’s ergonomically designed hand control, the user is free to remove the hand control from its holder for remote use or leave it cradled for hands-free operation. With a touch of a button you can select the object catalog, change the slew speed, view fascinating information about an object, or simply know if a desired object is visible in the sky.

About Celestron Maksutov-Cassegrain Telescopes
Celestron's
Maksutov-Cassegrain telescopes are similar to Schmidt-Cassegrain models
in regards to ease, durability, versatility, and minimal maintenance,
but trade smaller fields of view for better resolution in planetary
observation.
The Maksutov-Cassegrain is similar to the
Schmidt-Cassegrain with essentially the same advantages and
disadvantages. It uses a thick meniscus correcting lens with a strong
curvature and a secondary mirror that is usually an aluminized spot on
the corrector. The Maksutov secondary mirror is typically smaller than
the Schmidt's which gives it slightly better resolution for planetary
observing.
