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 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 which 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 make it easy to track objects even while when 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.

What can you see through this 127mm Celestron Schmidt-Cassegrain telescope?

With a relatively short 1250mm focal length and a light grasp 329 times that of the sharpest dark-adapted eye, the scope is capable of producing surprisingly bright wide-field images of the faint fuzzies outside the solar system – nebulas, galaxies, open star clusters, and more.
But those objects requiring high power and high contrast – globular clusters, close binary star pairs, lunar and planetary images, etc. – are not slighted in the least. Using optional eyepieces and/or a Barlow to boost the magnification, you can see subtle solar system details that are virtually invisible in smaller aperture scopes. You can study lunar craters, rilles, mountain ranges, and low contrast lunar ray detail. With reasonable seeing conditions, detail in Jupiter’s cloud belts and the Great Red Spot (actually closer in color to the Faint Pink Spot at this point in time) are visible, as are dusky markings on the face of Saturn and Cassini’s division in Saturn’s brilliant rings.
Optically and mechanically refined, and very reasonable in cost for famous Celestron C5 5” Schmidt-Cassegrain optics, this Celestron Omni XLT 127 has enough optical performance to keep you busy for the rest of your life.
