Discover the Telescope That’s Changing Amateur Astronomy Forever

The Celestron NexStar 90SLT is a computerized telescope designed for both novice and intermediate astronomers seeking a blend of portability, ease of use, and quality optics. Its 90mm Maksutov-Cassegrain optical design delivers sharp, high-contrast images, making it suitable for observing lunar details, planetary features, and terrestrial objects.

Optical Performance

The 90mm aperture, combined with a focal length of 1250mm (f/14), allows the NexStar 90SLT to provide detailed views of celestial objects. Users can expect to see lunar craters, the phases of Venus, Mars’ polar caps, Jupiter’s moons, and Saturn’s rings. The Maksutov-Cassegrain design is renowned for its ability to produce crisp images with minimal chromatic aberration.

Computerized Mount and Alignment

Equipped with a fully computerized Altazimuth mount, the NexStar 90SLT utilizes Celestron’s SkyAlign technology. This feature enables users to align the telescope by centering any three bright celestial objects in the eyepiece, simplifying the setup process. The NexStar+ hand control offers a database of over 4,000 celestial objects, allowing for easy navigation and tracking.

Portability and Assembly

The telescope’s compact form factor and quick-release fork arm mount facilitate easy transportation and assembly. The pre-assembled, adjustable stainless-steel tripod adds stability and can be set up without tools, making it convenient for spontaneous observing sessions.

Additional Features

The NexStar 90SLT includes a StarPointer finderscope to aid in alignment and object location. It also comes with a 25mm (50x) and a 9mm (139x) eyepiece, providing versatility in magnification options. Additionally, users receive a download of Starry Night Special Edition Astronomy Software, offering a 36,000-object database and enhanced images, including 3D renderings of stars, exoplanets, and galaxies.

Pros:

• User-friendly SkyAlign technology simplifies alignment.
• High-quality optics deliver sharp and detailed images.
• Compact and portable design suitable for various observing locations.
• Comprehensive database and computerized tracking enhance the stargazing experience.

Cons:

• The telescope requires 8 AA batteries for operation, which may necessitate frequent replacements.
• While the 90mm aperture is adequate for planetary and lunar observation, it may limit deep-sky object visibility compared to larger aperture telescopes.

In conclusion, the Celestron NexStar 90SLT offers a balanced combination of quality optics, user-friendly features, and portability, making it a valuable tool for amateur astronomers interested in exploring the night sky.
