The Gskyer 600x90mm AZ Astronomical Refractor Telescope is a solid choice for adults interested in astronomy, particularly those who are beginners or intermediate users. Its 90mm aperture and 600mm focal length allow for clear images of celestial objects, making it well-suited for stargazing and observing the moon and planets. The high-quality optics with fully coated glass lenses enhance image clarity and protect your eyes, which is a significant plus for long viewing sessions.

One of the standout features is the inclusion of three interchangeable eyepieces (24X, 60X, 120X) along with a 3x Barlow lens. This provides versatility in magnification options, allowing users to explore various celestial objects at different levels of detail. The adjustable aluminum tripod adds to the telescope's appeal, enabling users to find comfortable viewing positions easily.

The telescope weighs 18 pounds, which might be a bit heavy for some users looking for portability. While it’s relatively easy to operate, the manual focus might require some practice for those who are not familiar with telescopes. Additionally, the Azimuth mount may not be as stable as some more advanced equatorial mounts, potentially making tracking moving objects a bit more challenging.
