Orion Observer 90mm Equatorial Refractor Telescope

The Orion Observer 90mm Equatorial Refractor Telescope was designed for beginning astronomers looking for a telescope that can serve up vivid, sharp images of the Moon, planets, and brighter deep-space objects..

Orion Observer 90mm Equatorial Refractor TelescopeThe Observer 90 EQ’s fully antireflection coated 90mm-diameter (3.5″) front lens offers magnifying power suitable for those dipping their toes into observing. It includes starter set of 25mm and 10mm Plossl eyepieces.

The Orion Observer 90mm Equatorial Refractor Telescope offers the opportunity for lunar and planetary observing as well as more-distant objects such as the Orion Nebula, which at 36x, exhibits the four Trapezium stars as blue pinpoints surrounded by greenish gas.

The Observer 90 EQ features a 1.25″ rack-and-pinion focuser as well as a 90-degree star diagonal inserted in the focuser which provides a comfortable viewing angle. The 6×30 crosshair finder scope helps you locate your targets.

The Observer’s equatorial mount can be quickly polar-aligned to allow “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 your extra eyepiece and Barlow within easy reach.

The telescope weighs under 17 lbs. total, including the easily removable counterweight, so it’s easy to take outside for impromptu observing sessions.

An available upgrade includes a kit that offers extras like Orion’s MoonMap 260, power-doubling Shorty 2x Barlow Lens, Star Target Planisphere, and Color Filter Set.
