iOptron 90mm Mak-Cass Telescope

The iOptron® 90mm Maksutov-Cassegrain telescope is a powerful, yet compact and lightweight telescope that takes the stargazing experience into the stratosphere! The highest possible light transmission is ensured by multi-coatings applied to the curved front lens. Maksutov-Cassegrain Telescopes severely lessen the chromatic aberration that is a nuisance for their refractor cousins. The iOptron MC90, which has a focal length of 1200mm, performs much like a classic 90mm long-tube refractor despite its compact tube.

An internal flip mirror is included in the MC90 for dual viewing. Without exchanging equipment, users can locate, center, focus on a desired target with a 1.25" eyepiece, and photograph that object.

Two optical eyepieces, 10mm and 25mm, are included with the MC90 along with a 45º erect prism diagonal. The MC90 will fit any mount that accepts Vixen-style dovetails.
