Product Details

  • The Celestron CGEM II EQ Mount is renowned among the astronomy and astrophotography community. This computerized German equatorial mount (CGEM) is capable of carrying high-end and heavy-duty telescope systems up to 40-pounds, making the CGEM II able to accommodate most astronomers from those just starting out, to those who are buying their last mount. This equatorial mount is one of the best for both imaging and visual observing thanks to its vibration-free and durable design. Tracking is guaranteed to be smooth so that both viewing experience and your images will not be tarnished. Opt for the exceptional Celestron CGEM II when considering your next upgrade.

    Celestron CGEM II EQ Mount Head Design

    Built with a comfortable user experience in mind, the CGEM II (also called the CGEM2) is ergonomically friendly when it comes to both use and portability. Convenient to carry and easy to adjust with large Altitude and Azimuth knobs, you'll never again have to deal with the nuisance of small, flimsy knobs when getting ready for a night of imaging or stargazing. As an added bonus, you're essentially able to use any telescope OTA desired with this mount thanks to the dual saddle design. Whether you're employing a Vixen/CG-5 dovetail, or a Losmandy/CGE style, the CGEM II is perfectly compatible.

    Easy Alignment and Correction

    Celestron has implemented the innovative polar alignment procedure called All-Star, which allows you to choose any bright star for the mount to calculate its location. This makes for a smooth alignment process and gets rid of a lot of the hassle that comes with lower-end mounts. Another great feature of the CGEM-II, sure to please astro-imagers, is the Permanent Periodic Error Correction (PPEC) which lets you train the worm gears to effectively correct themselves the more they're used.

    Seamless Performance

    For objects near the Meridian (imaginary line passing from North to South), the CGEM-II mount will track well past the Meridian for uninterrupted imaging. With a robust database with over 40,000 objects, 400 user-defined programmable objects, and enhanced information on over 200 objects, the CGEM II has all bases covered to get rid of any hassle in the hobby.

    A weighty review.

    What can I say about a counter weight? It is doing what it was ment to do. Delivery was fast and in a timely manner.

    Good Reliable Mount

    I've had my CGEM II for about a year. I do mostly imaging with it and it tracks very well. Auto guiding is very effective. I usually run sub frames at around 30 second exposures but routinely run them for an hour or more. There is very little error during that time. I mount an 11 inch edge with hyperstar which is about the maximum the mount can handle. However I've never felt like it's overloaded even with camera, guide scope, asiair etc. hanging on it. Balance is important as I find you need to pick your target and then balance it with a slight over heavy on the front end. If you're having any trouble, spend a bit more time with balancing. Definitely a great mount for the price.

    Great for 2008, not 2021.

    I've had my CGEM II for now about 7 months, and it has been a mess to deal with. I would recommend this mount ONLY if you're doing strict visual observing, and not astrophotography, as this mount is IMPOSSIBLE to guide under 1.5-2" RMS I've hypertuned my mount, and it didn't help much. I'm using it with a C8 Edge HD, so not even loading it up, with perfect balance, and an Off-Axis-Guider, and it cant manage sub arcsecond guiding even on good nights, leaving me to do visual. Summary: A mount that looks sexy, seems promising, but fails to perform like its competitors- for nearly 100$ more, using technology that is far too outdated, (not even a USB port on the thing), and hostile towards astrophotographers using longer focal lengths. If you're looking at this mount, save the hastle, and the nearly 100$ extra for the CGEM, and go grab an EQ6R PRO, as it has a handle (doesn't sound like a lot, but trust me, it is NECESSARY for grab n go.), belt drives (A must for guiding), and so much more. I'm gonna go order my Astro-Physics Mach2GTO-L now.

    It's good

    The optics are worth the price of admission, Crisp, sharp everything you're hoping for. My only suggestion for Celestron is to go back to larger set screws for the mounting plate and accessories.

    cgem2 mount

    I wasn't sure if I should get my old mount fixed or get a new one. I dropped the old one while moving. I'm glad I invested in the new one. It's built like the proverbial brick ....house.
