Orion Observer 90mm Equatorial Refractor Telescope for Adults & Families

The Orion Observer 90mm Equatorial Refractor Telescope is an ideal choice for beginning skywatchers seeking a low-maintenance telescope that can deliver vivid, sharp images of the Moon, planets, and brighter deep-space objects. This wonderfully capable equatorial refractor telescope gives aspiring stargazers an exciting look at solar system favorites and beyond.

The Observer 90 EQ's fully antireflection coated 90mm-diameter (3.5") front lens boasts strong magnifying power. With the included 25mm and 10mm Plossl eyepieces, users will view distant worlds in high-contrast detail at 36x and 90x magnification. Jupiter's cloud bands are easily discernible, along with all four of its major moons. Saturn's rings appear sharp and dazzling.

While the Observer 90 EQ excels at lunar and planetary observing, it can also provide great views of many more-distant objects. At 36x, the Orion Nebula exhibits the four Trapezium stars as perfect blue pinpoints surrounded by greenish gas. Increasing the power to 90x with the 10mm eyepiece reveals the nebulosity spanning nearly the entire eyepiece field of view. In the summer sky, the Great Hercules Star Cluster (M13) starts to resolve into tiny stellar pinpoints.

The Observer 90 EQ features a 1.25" rack-and-pinion focuser for dialing in the sharpest view. A 90-degree star diagonal inserted in the focuser provides a comfortable viewing angle. The 6x30 crosshair finder scope helps users locate their targets.

The Observer's sturdy equatorial mount can be quickly polar-aligned to allow easy "tracking" of celestial objects as they move slowly across the sky, using just one of the two slow-motion knobs. Use both to center objects in the telescope's field of view. The extendable aluminum tripod provides solid support, and has an accessory tray to keep extra eyepieces and Barlow readily accessible.

Weighing under 17 lbs. total, including the easily removable counterweight, the Observer 90 EQ is highly portable, making it easy to take outside for impromptu observing sessions. This telescope's 90mm (3.5") lens optics and 900mm focal length excel for stunning views of the lunar surface, Saturn's rings, and bright deep-sky gems like the Great Hercules Cluster.

The sturdy EQ3-class equatorial mount and aluminum tripod represent a significant upgrade from the mounts that come with comparable telescopes on the market. Two quality 1.25" Plossl eyepieces, a 25mm for low-power views at 36x and a 10mm for higher magnification at 90x, are also included.
