Description

21090 Omni XLT 120 Telescope by Celestron

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.

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
1.25" star diagonal
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
