CELESTRON - Omni XLT 150 Newtonian Reflector Telescope (31057)

The Celestron Omni XLT 150mm Reflector has excellent light gathering power of 459x, taking advantage of the light gathering power inherent in newtonian reflectors. On top of this, Celestron has incorporated their StarBright XLT coatings to improve light transmission. The optical tube is mounted on the Omni CG-4 Equatorial Mount which includes setting circles for adjusting declination and right ascension. Setup is quick and no tools are needed. Simply mount the optical tube on the mount and extend the stainless steel tripod legs. A 25mm 50° eyepiece is included as well as a 1.25" diagonal.


  • High quality optics start with each lens and(or) mirror being hand selected so only the finest grade of optical glass is used
  • StarBright XLT coatings provide maximized light transmission
  • 1.25" star diagonal
  • 25 mm multi-coated eyepiece - 20 mm eye relief, 50° FOV
  • CG-4 German Equatorial mount with setting circles and slow motion controls - to accurately locate and track sky objects
