The Orion Observer 90mm Equatorial Refractor is an excellent choice for beginning skywatchers looking for a telescope that can serve up vivid, sharp images of the Moon, planets, and brighter deep-space objects. This refractor features a 90mm-diameter fully antireflection coated achromatic lens of 900mm focal length, delivering views at 36x and 90x magnification with the included 25mm and 10mm 1.25" Plossl eyepieces. Refractor telescopes are coveted for their crisp, sharp images and their lack of maintenance compared to reflector telescopes, whose optics must be regularly re-aligned or collimated. The kit includes a German equatorial mount with a 4 lb. counterweight, dual slow motion control knobs, and a sturdy aluminum tripod with a snap-in accessory tray.
