Orion Apex 90mm Min-EQ Maksutov Cassegrain Telescope Kit with Eyepiece & Software, 90mm Optical Diameter, f/13.9 Focal Ratio

The Orion Apex 90mm Min-EQ Maksutov-Cassegrain Telescope design permits large-diameter optics, 90mm, to be housed in an unusually compact, wonderfully portable tube. As a spotting scope, the Apex 90 gathers more light than typical field scopes, serving up brighter, more highly resolved images even in the dimmest of lighting conditions. Multi-coatings applied to the curved front lens guarantee the highest possible light transmission.

For astronomy, the Apex telescope exhibits all the performance of classic long-tube 90mm refractors and easily outperforms smaller refractors on views of the planets and Moon as well as on faint nebulas and star clusters. Its long focal length allows high-power study of Jupiter's cloud belts and Red Spot and Saturn's rings and provides long reach for capturing distant terrestrial targets. The Apex telescopes accept standard 1.25" telescope eyepieces for nearly unlimited magnification options. The Apex 90 comes with a multi-coated 25mm Sirius Plossl eyepiece (1.25") and a 45° diagonal that provides a correctly-oriented field of view, as does the correct-image finder scope.

The scope easily pops on and off the sturdy Min-EQ equatorial mount which features an all-metal EQ-1 equatorial head perched on a tripod with three thread-on legs. It includes counterweight, dual slow-motion cables, latitude adjustment and 1/4"-20 adapter.
