  • Aspheric shaping for reduced aberration
  • StarBright XLT optical coatings
  • CG-4 German equatorial mount
  • Ball bearings in both axis of the mount


  • What's Included

    Telescope, Eyepiece, Tripod


    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 include: 


    • 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, 50-degree 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
    • The Sky Level 1 planetarium software with 10,000 object database and enhanced images



    About Celestron Reflector Telescopes

    A Newtonian reflector uses a single concave mirror as its primary. Light enters the tube traveling to the mirror at the back end. Light is then "bent" forward in the tube to a single point, its focal plane. A flat mirror called a "diagonal" intercepts the light and points it out the side of the tube at right angles to the tube through the eyepiece. The eyepiece is placed there for easy viewing. Newtonian Reflector telescopes replace heavy lenses with mirrors to collect and focus the light, providing much more light gathering power for the money.

    You can have focal lengths up to 1000 mm and still enjoy a telescope that is relatively compact and portable. Newtonian Reflector telescopes do require more care and maintenance because the primary mirror is exposed to air and dust. However, this small drawback does not hamper this type of telescope's popularity with those who want an economical telescope that can still resolve faint, distant objects. Newtonian reflectors produce a "right-side-up image" but the image will appear rotated based on the location of the eyepiece holder in relation to the ground. Newtonian reflectors are best for astronomical use where right-side-up does not matter.


    Newtonian Advantages


    • Lowest cost per inch of aperture compared to Refractors and Catadioptrics since mirrors can be produced at less cost than lenses in medium to large apertures
    • Reasonably compact and portable up to focal lengths of 1000 mm
    • Excellent for faint deep sky objects such as remote galaxies, nebulae and star clusters due to the generally fast focal ratios (f/4 to f/8)
    • Adequate for lunar and planetary work
    • Good for deep sky astrophotography (but not as convenient and more difficult to use than Catadioptrics)
    • Free of color aberration due to the use of a primary mirror

    Newtonian Disadvantages


    • Generally not suited for terrestrial applications
    • Slight light loss due to secondary (diagonal) obstruction when compared with Refractors

Customer Q&A

1 - 5 of 12
1 2
  • Q1: Can it be used for terrestrial viewing?

    A: No. The Omni XLT 150 is a reflective telescope. Because of the mirror system this telescope flips the image you see upside down and backwards. If you would like to use this telescope for viewing land objects you will need to purchase an erecting prism to correct the image.

  • Q2: Can you order this with a motor drive?

    A: Yes, we do carry a motor drive for this mount.  The item number for this motor drive is CELE228.
