Celestron Omni XLT 127 Telescope

Omni XLT 127 - (5 Inch) Schmidt-Cassegrain Telescope on CG-4 Equatorial Mount

The Celestron Omni XLT 127 features a Schmidt-Cassegrain optical design coupled with the Celestron Omni CG-4 heavy-duty German Equatorial mount. The sturdy tripod features 1.75 Inch adjustable stainless steel legs and a center accessory tray for superior rigidity and vibration dampening. Along with the stable platform of the CG-4 mount the Omni XLT 127 features high-quality optics. Using aspheric shaping technology in conjunction with hand-figuring the optics the Omni XLT presents an image with virtually no spherical aberration. Celestron has also added their famous StarBright XLT coating system to further enhance light transmission.

At the heart of the Celestron Omni 127 XLT, is a high-quality Schmidt-Cassegrain style telescope with a hand-chosen lens for absolutely the best optics available. We're talking about a 5 Inch aperture with a limiting stellar magnitude of 12.9 and 0.97 arcseconds of resolving power. Couple that with a 1250 mm focal length and a focal ratio of f/9.8 it presents an image with virtually no spherical aberration. With superior optics and a stable platform, the Celestron Omni XLT series is a great choice for astrophotography. Use the optional dual-axis motor drive (#93522) and polar axis finder (#94221) to track objects for long exposure photography. This handsome scope comes backed with a two year Celestron warranty and will endure as long as your fascination with the Cosmos!

Questions & Answers

Ask a Question
  • Can this scope be fitted with a larger 2" diagonal so you can use 2" lenses?

    Hello, The focuser is 1.25" in diameter so no chance for 2" accessories.

  • Can the Celestron 11084 Omni XLT - 127 be used for astrophotography with a DSLR? Thank you.

    Yes, but additional accessories will be needed. You would need a dual axis motor kit https://www.optcorp.com/catalogsearch/result/?q=CG-4+Mount+Dual+Axis+Motor+Drive to allow long exposures, and then you would need a T-adapter https://www.optcorp.com/cel
