The Omni XLT telescope 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. Using Celestron's famous StarBright XLT coating system, light transmissions are further enhanced.

With an easy no-tool setup, the Omni telescope has a heavy-duty pre-assembled stainless steel tripod featuring 1.75" legs, accessory tray and bubble level. Similar to spirit level, bubble level allows you to tell if the mount is resting on a completely flat surface.

There are ball bearings in both axis of the telescope mount for a smooth performance. The CG-4 German Equatorial mount with setting circles and slow motion controls allows you to accurately locate and track sky objects.

The 1.25" star diagonal helps prevent neck strain by angling the eyepiece. This premium refractor telescope comes with a 25 mm multi-coated eyepiece with 20 mm eye relief.

Ships to Australia and New Zealand only.
