This eliminates the need for star charts or compasses, allowing you to spend more time observing and less time setting up.

Included with the telescope is a free download of Starry Night Special Edition astronomy software. This interactive sky simulation program enhances your stargazing experience by providing a virtual planetarium on your computer. Explore the lunar surface, marvel at Saturn’s rings, or observe the Great Nebula in Orion with this powerful software.

When it comes to optical performance, the NexStar 90SLT truly shines. Its Maksutov-Cassegrain design with a focal length of 1250mm delivers crisp and clear views of the Moon, planets, and deep space objects. Whether you’re observing the intricate details of the lunar surface or pushing the magnification to view Saturn’s rings, this telescope will exceed your expectations.

While the NexStar 90SLT offers exceptional optics and user-friendly features, it’s important to note a couple of drawbacks. The battery life with standard AA batteries is relatively short, so investing in a rechargeable 12-Volt battery is recommended for extended observing sessions. Additionally, setting up a computerized telescope may require some practice to ensure accurate alignment.

In conclusion, the Celestron NexStar 90SLT Computerized Telescope is an excellent choice for both seasoned astronomers and beginners alike. Its compact and portable design, combined with powerful optics and user-friendly features, make it a versatile and reliable tool for exploring the wonders of the night sky.
