Celestron NexStar 90SLT GoTo Telescope

Astronomy is more than just stargazing. Ask anyone studying Astrophysics and they will tell you just how complex and impressive the night sky can be. You need the proper instruments to fully view the wonders of the Universe and that is where the telescope comes to play. The Celestron NexStar 90SLT GoTo Telescope will introduce you to the night sky and show you everything it has to offer.

With a preassembled, adjustable stainless steel tripod and quick release fork arm and tube, the NexStar 90SLT telescope 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!


The high quality 90 mm Maksutov-Cassegrain optical tube assembly allows for stunning views with a focal length of 1250 mm. Use the included StarPointer finderscope to help with alignment and accurately locating objects in the night sky. This telescope is good for terrestrial and celestial observing, making it a favorite among amateur and intermediate astronomers.

Intelligent Design

The mount features a fully computerized Altazimuth base for the finest views in all directions. A sturdy stainless steel tripod with an accessory tray comes with the OTA for easy support of the mount and to hold eyepieces or other small accessories. There is an auxiliary port located on the mount for additional accessories such as the GPS accessory.

The database allows the telescope to locate over 4,000 celestial objects and there is a bonus Astronomy Software download available with a 10,000 object database, printable sky maps and 75 enhanced images.

Powered by 8 AA (not included) batteries or an optional AC adapter, the NexStar 90SLT GoTo Telescope loves to travel. 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.

Hand Control

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.

Your telescope includes NSOL telescope control software for basic control of your telescope via computer (with optional RS-232 cable). It is also compatible with an optional NexRemote telescope control software, for advanced control of your telescope via computer.


Using Celestron’s patented SkyAlign, simply input the date, time and location into the hand control then slew the telescope to any three bright celestial objects in the sky, making for a fast and easy alignment process. You do not need to know the names of the stars – you can even pick the Moon or bright planets!
