Celestron support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I align my Finderscope?

    To align the StarPointer finderscope, perform the process during the day using a distant stationary object like a streetlight. Center the object in the main telescope eyepiece first, then adjust the finderscope knobs until the red dot is centered on the same object.

  • Can I look at the Sun through my telescope?

    No, never look directly at the Sun with the naked eye or through a telescope unless you have a proper, professionally made solar filter covering the front aperture. Permanent eye damage can result instantly.

  • Where can I find manuals and software updates?

    You can download the latest product manuals, drivers, and firmware updates directly from the 'Manuals & Software' section of the Celestron website.

  • How long is the warranty on Celestron products?

    Celestron typically offers a 2-Year or Limited Lifetime Warranty on most products. Specific terms depend on the product model and can be verified on the Celestron warranty page.

  • What should I do if my telescope does not track objects correctly?

    Ensure your telescope is properly aligned (SkyAlign or Polar Align) and that the power source is adequate. For computerized mounts, check that the location and time settings are accurate on the hand control or app.
