Product Description

CELESTRON - Omni XLT 150mm Optical Tube Assembly 6" (31057-1)

The new Celestron Omni XLT Series features  the latest in hybrid refractor, reflector and Schmidt-Cassegrain optical designs .  Using aspheric shaping technology in conjunction with hand-figuring the optics, the Omni XLT presents an image with virtually no spherical abberation. Celestron has also added their famous StarBright XLT coatings to further enhance light transmission.  The mirrors are fully coated with multiple layers of high reflectivity aluminum. The aluminum coatings are then enhanced with titanium dioxide and overcoated with a protective layer of silicon monoxide for long life. These are the same mirror coatings used on Celestron’s largest and most expensive telescopes.

A 750mm focal length and focal ratio of f/5 presents an image ideal for both visual and astrophotography use .  It also comes with a 1.25" star diagonal, 1.25" rack and pinion focuser, and high quality Celestron 25 mm Plossl eyepiece.  The  finderscope is a straight-thru 6 X 30mm achromat.

 OPTIONAL:  This  can be mounted to most all CGEMs / Tripods via its Vixen style dovetail bar, however, it is best matched to Celestron's CG-4 Equatorial Mount (product #91509).  This mount can be further up-graded to Celestron's Dual-axis Motor Drive/ Drive Corrector  (#93522) - essential for astrophotography.  An optional Polar Axis Finder  (#94223) is also available to increase the accuracy of your alignment.

  • High quality optics start with each lens and mirror being hand selected so only the finest grade of optical glass is used.
  • StarBright XLT coatings provide maximized light transmission. 
  • A great choice for exploring the amazing world of astrophotography.
  • Includes a two year Celestron Warranty
