Celestron NexStar SLT 90 Mak telescope

The NexStar SLT 90 Mak is a computer-controlled GoTo telescope, suitable for both beginners and slightly more experienced stargazers. With it, you can see details on the Moon’s surface, the phases of Venus, the polar ice caps on Mars, Jupiter’s four moons and Saturn’s rings.

Alignment without a star chart

With Celestron’s patented SkyAlign alignment system, you enter the date, time and location into the hand controller and then point the telescope at any three bright celestial objects. You don’t need to know the names of the stars, as the Moon and bright planets can also be used as alignment points.

Power supply and hand-held controller

The telescope is powered by eight AA batteries or a separately available mains adaptor (#18778). The internal battery compartment supplies power to the precision servo motors, and the cable from an external battery pack cannot become tangled around the mount. The ergonomic hand controller can be removed from its holder or left in place; it is used to select the object list, adjust the rotation speed, read information about objects and check whether the desired object is visible in the sky.

Main features

• The GoTo control system moves the telescope to the object selected from the hand controller’s object list.
• This ready-assembled, adjustable stainless steel stand can be set up in minutes without the need for tools.
• The quick-release fork arm and tube make assembly and disassembly quick and easy.
• The long focal length of Maksutov-Cassegrain optics brings out the fine details of the planets and the Moon.
• Servo motors ensure that movements remain smooth and vibration-free during observation.
• Battery operation makes it possible to carry out observations even in places where mains power is not available.
