About the Orion 127 Maksutov Cassegrain

The Orion StarMax 127mm Equatorial Mak-Cass Telescope has light-folding Maksutov-Cassegrain optical design and big 127mm (5") aperture for delivering high-resolution imaging performance in a tube only 14.5" long. The included AstroView equatorial mount provides more than ample support for high-magnification study.

With 55% greater light-gathering capacity than a 4" scope and double that of a 90mm, the hundreds of deep-sky objects plotted on your star atlas now become willing targets. On the other hand, the scope's long 1540mm focal length (f/12.1) permits magnifications upwards of 250x with optional eyepieces, allowing study of surface features on Mars and ring detail on Saturn. Internal tube baffling and multi-coatings on the meniscus lens maximize image contrast and brightness. The seamless aluminum tube is enameled a rich metallic burgundy and fitted with quality aluminum front and rear cells.

A built-in, two-bolt 1/4"-20 plate assures rigid coupling to the mount (or to a tripod for terrestrial use). Aluminum focus knob with rubber grip. Aluminum eyepiece holder with two large thumbscrew locks. Quality 25mm (62x) Sirius Plossl eyepiece (1.25") and mirror star diagonal. A 6x26 correct-image achromatic finder scope with aluminum dovetail bracket. Even a padded carrying case. Optional EQ-3M single and dual-axis electronic drives allow hands-free tracking.
