Celestron AstroMaster 90EQ Review: A Reliable Refractor Telescope for Beginner Stargazers

This refractor telescope is designed with beginners in mind, delivering sharp images of celestial objects like the Moon, Jupiter’s moons, Saturn’s rings, Venus phases, and even deep-sky targets like the Orion Nebula or the Andromeda Galaxy under dark skies.

Whether you're a hobbyist, a student, or a parent introducing astronomy to kids, the AstroMaster 90EQ provides a solid balance of affordability, portability, and optical performance. Plus, its manual German equatorial mount makes celestial tracking both educational and rewarding.

Product Highlights: Key Features of the AstroMaster 90EQ and What to Look for

1.90mm Aperture and Fully Coated Optics

With a 90mm aperture, this refractor telescope collects ample light for planetary viewing. Fully coated glass optics ensure high-contrast images with minimal chromatic aberration.

2.German Equatorial Mount

The manual EQ mount with slow-motion controls allows for accurate tracking of celestial objects, teaching users how to follow the Earth's rotation — a skill important for any amateur astronomer.

Unlike many telescopes, the AstroMaster 90EQ can also be used for daytime terrestrial viewing, such as observing birds or distant landscapes.

4. Included Accessories

  • Two eyepieces (typically 10mm and 20mm)
  • StarPointer™ red dot finderscope
  • Sturdy tripod with accessory tray
These included tools reduce your need for additional investments right out of the box.

5.Budget Considerations

Priced reasonably for a refractor with equatorial mount, this telescope sits in the sweet spot for entry-level users who want long-term value without breaking the bank. It’s a practical step up from cheap department store telescopes.
