CGX

I'll just post a link to Celestrons product page about the CGX mount. It should speak for itself why this is a desirable upgrade.

Belt drive, Internal wiring, high load capacity, spring adjusted worm gear tension, NexStar+ Remote control and more.

Most mount, sometimes suffer of problem like some material selections, poor QC etc that means a so called “hypertune” is a something to consider. https://www.deepspaceproducts.com/ is the main go-to guy here I believe, but the service can surely be done on other places. You can also order DIY kits for it.

The usual done is: bearings are changed for better options, as well as grease lubricants. Low-frictions surfaces, such as washers etc are usually changed from nylon, or similar, to Teflon. All moving axis are then torqued to a value that is not over-tight which can cause tension in the moving parts.

The result is a mount with axis that moves very smooth and easy. All “jerky”, or “sticky” motion is usually gone and the mount runs very smooth.

This is where I stand. As one may see on the video where I compare the hypertuned CGEM mount with the new CGX mount there is a huge difference in how easy the axis turns.

The DEC axis was actually so hard that balancing would be very difficult. The RA axis was not as sticky, but during a test with test with a telescope and a OAG it was obvious that the RA axis had a minor spiky motion and a reoccurring larger drift spikes.

This was not good news. Luckily I did the videos to easy explain the issue and got a ticket with Celestron tech support going.

Thanks to good response I have now sent the mount away for service with the supplier and I hope they will get it fixed easily.

Go to the YouTube channel for some more a more up-close un-boxing experience.
