Celestron's Omni XLT 127mm f/10 Schmidt-Cassegrain EQ Telescope is ideal for users who want a compact and powerful observation platform that is able to achieve high magnifications for detailed views of the Moon and planets as well as have the ability to reach out past our solar system to discover deep-sky objects such as nebulae and galaxies.
The Schmidt-Cassegrain design, coupled with the proprietary Starbright XLT optical coating system, corrects aberrations like comas and chromatic aberration to produce clear and crisp, high-contrast images with true color rendition. For its compact 11" length, it features a long 1250mm focal length, giving it a high magnification potential, and its large aperture ensures the resolution required to see dim deep-space objects that smaller apertures are unable to see. The scope is outfitted with an internal focusing mechanism that accepts the included 1.25" 90° star diagonal. Celestron includes a 25mm eyepiece that yields a moderate 50x magnification to get new users started.
The included manual equatorial mount features large slow-motion knobs that make it easy to track objects even while wearing gloves, with setting circles on both axes for alignment and celestial navigation. The Omni mount includes a Vixen-style dovetail for mounting other optical tubes, and an adjustable-height stainless steel tripod with large and sturdy 1.75"-diameter legs and an accessory tray that acts as a leg spreader for the tripod to add stability and reduce vibrations.
