iOptron

90mm Refractor - Black

# 8711

The iOptron^® 90mm OTA (R90) is a great astronomy telescope that is a powerful yet portable enough to take anywhere. With fully multi-coated achromatic optics, the R90 reveals brighter and sharper images. The wide field of view of a 90mm objective lens and short 500mm (f/5.6) focal length are perfect for night sky observation, making it ideal for Moon, planets and larger deep-sky objects.

Comes with 2 optical eyepieces (10mm and 25mm) and a 45º erect prism diagonal, the R90 is also a good portable scope for bird watching and terrestrial observation. The equipped dovetail makes it fit to any telescope mount that accepts Vixen-style dovetail.

The R90 is an excellent mate for iOptron's Cube^TM or CubePro^TM GOTO telescope mount.
