Celestron CGEM II Series GoTo Equatorial Mount


The Celestron CGEM mount has been a very popular EQ telescope mount for several years, but never a company to “gather moss”, it was decided that the Celestron CGEM should have a make-over on the outside and the inside.

At first glance, one can see that the Celestron CGEM II equatorial mount is more ergonomic than its predecessor, with longer lock levers to make it easier to make adjustments to your mount. Also, the new heavy duty dual-style saddle plate is designed to accept either CG-5 (Vixen) or CGEM (Losmandy) mounting dovetails so that virtually any optical tube assembly can be mounted in minutes without the need for an adapter.

This EQ telescope mount has a generous weight capacity of 40 pounds. You can ride up to an 11” EdgeHD OTA on this portable yet sturdy mount, but still easily break it down into manageable pieces for travel to star parties or dark sky sites near you. The Celestron CGEM II equatorial mount weighs 40 pounds without counterweights and the tripod, which has also been updated, weighs just 20 pounds.

Speaking of the tripod, this one has 2” stainless steel legs for rigidity and support, and has graduated markings on each leg to make leveling fast and easy. The spreader bar pushes against the legs to make them amazingly sturdy, and the interior of the spreader offers receptacles for a few extra eyepieces so they are in easy reach when observing.

The electronics of the Celestron CGEM II Equatorial Mount, whether designed for the previous CGEM or new to the CGEM II model, will allow you to set up, use, and maintain your EQ telescope mount with these innovative features:

  • A built-in All-Star Polar Alignment program lets you accurately polar align on any star in the sky without having a view of the celestial pole. No polar finderscope necessary!
  • This EQ telescope mount tracks past the meridian for seamless imaging across the best part of the sky.
  • With PPEC, or Permanent Periodic Error Correction, you can train out the periodic error on your worm gears once, and the system will remember the PEC recordings.
  • This EQ telescope mount is capable of slewing at 5 degrees per second, getting you where you want to go fast!
  • There is a USB 2.0 port on the bottom of the NexStar GoTo controller to allow you to not only update the firmware of both the controller and the mount, but to connect directly to a PC with your own ASCOM-supported software.
  • With the touch of a button you can visit over 40,000 stars, galaxies, nebulae, planets, clusters, and more. The built-in celestial database also allows for 100 user-defined objects and will give you expanded information on 200 of the best objects in the sky.
