iOptron R90 90mm f/5.6 Doublet Refractor Telescope (OTA Only)

The R90 90mm f/5.6 Doublet Refractor Telescope from iOptron features a doublet achromatic lens system with their proprietary anti-reflection fully multicoated optics to produce images with reduced chromatic and spherical aberrations for clear and bright images without distortion across the entire field of view, with true color rendition. This is a versatile optical tube assembly that can be employed as a simple grab-and-go primary telescope, or as a terrestrial spotting scope. It has a fast f/5.6 focal length which makes it ideal for astrophotography of the Moon, planets, or bright and large deep-sky objects.

Two included eyepieces yield magnification of 20x and 50x, and the rack-and-pinion focuser accepts any other 1.25" eyepieces and accessories adding to its versatile nature. An included 45° erect-image diagonal corrects images horizontally and vertically when using the OTA as a spotting scope. The scope is offered without a mount or tripod, but an included Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle.
