  • Celestron Omni CG-4 Telescope Mount and Tripod

    The Celestron Omni CG-4 Telescope Mount and Tripod provides a stable and reliable foundation for small to medium-sized telescopes, combining a total of 11 lbs of counterweights with a heavy-duty tripod featuring 1.75" steel legs. This German Equatorial mount is engineered for astronomical tracking, allowing you to follow stars and planets across the sky with smooth, controlled motions using the included RA and DEC slow-motion controls.

    CG-4 German Equatorial Head: 11 lbs of Counterweight

    The core of the Omni CG-4 is its German Equatorial design, which simplifies tracking by aligning with Earth's axis of rotation. Once polar aligned, you only need to make adjustments in Right Ascension (RA) to keep objects centered in the eyepiece. The mount includes both a 7 lb and a 4 lb counterweight, giving you the flexibility to perfectly balance a wide range of optical tubes for smooth, strain-free operation.

    • Dual Slow-Motion Controls: Make fine adjustments to the telescope's pointing in both Right Ascension and Declination. This precision is essential for centering planets at high magnification or keeping a guide star centered during long-exposure astrophotography.
    • Setting Circles: RA and DEC setting circles allow you to locate celestial objects using their celestial coordinates from a star chart or planetarium app. This classic method of "star-hopping" is a valuable skill for any astronomer to learn.

    1.75" Steel Tripod for Vibration Damping

    A steady mount is only as good as its tripod, and the Omni CG-4 stands on a heavy-duty, pre-assembled steel tripod with 1.75" diameter legs. This robust construction is superior to the aluminum tripods found on many entry-level mounts, providing the rigidity needed to damp vibrations quickly. A stable view is critical, especially at high powers, and the CG-4's solid foundation ensures that breezes or minor bumps don't ruin your observations.

    • Adjustable Height: The tripod legs are adjustable, allowing you to set a comfortable viewing height whether you're standing or seated.
    • Accessory Tray: A sturdy center brace locks the tripod legs in place for maximum stability and features a convenient accessory tray to hold your eyepieces, filters, and other small items, keeping them organized and within easy reach.

  • What is the payload capacity of the Omni CG-4 mount?

    While Celestron doesn't specify an official payload capacity, the Omni CG-4 is generally recommended for optical tubes weighing up to around 20 lbs for visual use. For astrophotography, it's best to keep the total equipment weight (telescope, camera, guidescope) under 10-12 lbs to ensure stable tracking.

    Can I motorize the Celestron Omni CG-4 mount?

    Yes, the Omni CG-4 is compatible with Celestron's optional dual-axis motor drive (model #93522). This accessory adds motors to both the RA and DEC axes, allowing for hands-free tracking of celestial objects and electronic adjustments using a hand controller.

    What types of telescopes can I use with the Omni CG-4?

    The Omni CG-4 uses a standard Vixen-style dovetail saddle. This makes it compatible with a wide variety of optical tubes, including 4" to 6" refractors, 5" to 8" Schmidt-Cassegrains, and 6" to 8" Newtonian reflectors, provided they are equipped with a V-style dovetail bar and fall within the mount's practical weight capacity.

    How do I polar align the Omni CG-4 mount for tracking Jupiter?

    To track a planet like Jupiter, you first need to perform a basic polar alignment. Adjust the mount's altitude axis to match your latitude and point the RA axis towards Polaris, the North Star. Once aligned, the mount's RA slow-motion control will allow you to easily follow Jupiter's east-to-west movement across the sky.

    Is the Omni CG-4 a good mount for a 6" f/5 Newtonian telescope?

    Yes, a 6" f/5 Newtonian is an excellent match for the Omni CG-4 for visual observing. The optical tube typically weighs around 12-15 lbs, which the mount can handle comfortably. The 11 lbs of included counterweight should be sufficient to achieve proper balance.

    What is the difference between the CG-4 and a lighter-duty CG-3 or EQ-2 mount?

    The primary difference is stability and capacity. The Omni CG-4 features a more substantial mount head, larger worm gears for smoother motion, and a much heavier tripod with 1.75" steel legs. This results in significantly better vibration damping and the ability to carry heavier telescopes compared to lighter equatorial mounts.
