About this product

Model:  cel_omni_150r
Part Number:  21094

150mm (6") f/5 Refractor on a CG-4 Equatorial Mount.

Omni XLT series features the stable platform of the CG-4 mount and 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. We also added our famous StarBright XLT coating system to further enhance light transmission.

FEATURES

  • 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
  • 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
  • Ball bearings in both axis of the mount for smooth performance
  • Heavy-duty pre-assembled stainless steel tripod featuring 1.75" legs, accessory tray and bubble level
  • Easy no-tool setup
