Outline
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 abberation.

  • 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.
  • 25mm multi-coated eyepiece - 20mm eye relief, 50o FOV.
  • 1.25" star diagonal.
  • CG-4 German Equatorial Mount with setting circles and slow motion controls - to accurately locate and track sky objects.

  • Heavy-duty pre-assembled stainless steel tripod featuring 1.75" legs, accessory tray and bubble level.
  • Easy no-tool setup.
