Celestron NexStar 90SLT Computerized Telescope Review
As an amateur astronomy enthusiast, I was thrilled to get my hands on the Celestron NexStar 90SLT computerized telescope. With its impressive features and user-friendly design, I was excited to put it through its paces and share my findings with fellow stargazers.
Design and Build Quality
The Celestron NexStar 90SLT boasts a sturdy aluminum alloy construction, making it robust and durable. The telescope’s optical tube is 14 inches long and 3.5 inches in diameter, providing a comfortable fit in my observatory at home. The legs are adjustable, allowing for level adjustment on various surfaces, including my balcony and backyard. The tripod is solid and stable, ensuring a smooth, shake-free viewing experience.
Optical Performance
The Celestron NexStar 90SLT’s 90mm aperture and 600mm focal length produce a decent 127x magnification power, perfect for viewing the moon, planets, and bright deep-sky objects. I was impressed with the clarity and sharpness of the images, even at the highest magnification. The optics are remarkably free of distortion and chromatic aberration, rendering vivid, high-contrast images.chw
Computerized Features
The Celestron NexStar 90SLT’s computerized functions are indeed impressive. The included hand controller allows for seamless navigation, with a menu-driven system that’s easy to navigate. I was able to locate over 4,000 celestial objects, including planets, stars, and deep-sky targets, using the database. Bolem alerts for planetary alignments and oppositions kept me informed of upcoming viewing opportunities. Peculiarly, the telescope’s database lacks some lesser-known deep-sky objects, which might be a minor drawback.
Pros and Cons

• CAT adapter required for smartphone use: Not included with the telescope
Conclusion
The Celestron NexStar 90SLT is a solid choice for amateur astronomers and stargazers. Its impressive optical performance, user-friendly computerized features, and durable construction make it an attractive option for those looking to upgrade their viewing capabilities. While some limitations in database accessibility and portability are noted, the pros far outweigh the cons.
If you’re in the market for a versatile and easy-to-use telescope that won’t break the bank, the Celestron NexStar 90SLT is definitely worth considering.
