About the Orion StarMax 127mm Equatorial Maksutov-Cassegrain Telescope...
For the serious astronomer who values performance and quality optics but wants portability and easy set-up, the Orion StarMax 127mm Equatorial Maksutov-Cassegrain Telescope is ideal.
Credit its light-folding Maksutov-Cassegrain Orion Telescope optical design and big 127mm (5") aperture for delivering high-resolution astrophotography performance in a tube only 14.5" long! And with the included AstroView equatorial Orion Telescope Mount providing more than ample support for high-magnification study, the Orion StarMax 127mm Equatorial Maksutov-Cassegrain Telescope will turn a stargazing pastime into a passion.
With 55% greater light-gathering capacity than a 4" Orion Telescope 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 Orion StarMax 127mm Equatorial Maksutov-Cassegrain Telescope'''s long 1540mm focal length (f/12.1) permits magnifications upwards of 250x with optional telescope 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. This Orion Telescope simply doesn'''t compromise.
The same can be said for the Orion StarMax 127mm Equatorial Maksutov-Cassegrain Telescope'''s construction and accessories. No cheap plastic here as on competitors''' offerings, just back-to-basics Orion Telescope quality. 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 Orion Telescope Mount (or to a tripod for terrestrial use). Aluminum focus knob with rubber grip. Aluminum telescope eyepiece holder with two large thumbscrew locks. Quality 25mm (62x) Sirius Plossl telescope 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 Orion Telescope Mount single and dual-axis electronic drives allow hands-free tracking.
The Orion StarMax 127mm Equatorial Maksutov-Cassegrain Telescope will quickly become the most frequently used Orion Telescope you'''ll ever own!
