NEXSTAR 90SLT Maksutov-Cassegrain

Presenting the Celestron Nexstar 90SLT Maksutov-Cassegrain

The Celestron Nexstar 90SLT Maksutov-Cassegrain Telescope is a computerized telescope designed for both amateur and intermediate astronomers. Here are some key features and information about this telescope:

Optical Design: The Celestron Nexstar 90SLT uses a Maksutov-Cassegrain optical design, which is a type of catadioptric telescope. This design combines both lenses and mirrors to create a compact and versatile telescope that provides a sharp and clear image.

Aperture: The aperture of the Celestron Nexstar 90SLT is 90mm (3.5 inches), which is relatively small compared to some other telescopes. However, the Maksutov-Cassegrain telescope design allows for a long focal length, which helps to increase the telescope’s magnification and makes it ideal for planetary and lunar observation.

Focal Length: The focal length of the Celestron Nexstar 90SLT is 1250mm, which is quite long for a telescope of this size. This allows for higher magnifications and provides clear and detailed views of the moon, planets, and other celestial objects.

Mount: The Celestron Nexstar 90SLT comes with a computerized altazimuth mount, which allows for easy and precise movement of the telescope. The mount has a database of over 4,000 celestial objects, which can be accessed through the handheld controller.

GoTo System: The Celestron Nexstar 90SLT has a GoTo system, which means that it can automatically locate and track celestial objects. This system uses a database of celestial objects, which includes stars, planets, galaxies, and more. Once the user selects an object, the telescope will automatically move to the correct position and track the object as it moves across the sky.

Eyepieces: The Celestron Nexstar 90SLT comes with two eyepieces – a 25mm and a 9mm. The 25mm eyepiece provides a wider field of view, while the 9mm eyepiece provides higher magnification.

Finder Scope: The Celestron Nexstar 90SLT comes with a red dot finder scope, which makes it easier to locate celestial objects.

Accessories: The Celestron Nexstar 90SLT comes with several accessories, including a stainless steel tripod, a star diagonal, and a software program called “The SkyX – First Light Edition.”

Overall, the Celestron Nexstar 90SLT Maksutov-Cassegrain is a versatile and easy-to-use telescope that is suitable for both beginners and intermediate astronomers. Its computerized GoTo system, compact design, and long focal length make it ideal for planetary and lunar observation, as well as some deep sky observation.
