Product Overview

Celestron 9.25" EdgeHD SCT on CGEM II GoTo EQ Mount

Freshly upgraded CGEM II Equatorial Mount with 9.25" EdgeHD Schmidt-Cassegrain Telescope. Celestron has improved upon the already much appreciated CGEM mount substantially. The CGEM II now contains a more user-friendly design that includes a dual-style dovetail saddle and longer lock levers. Other new components include a USB 2.0 powered PC connection with hand controller, Permanent Periodic Error Correction and an independent autoguiding port.

Celestron CGEM II GoTo Equatorial Mount

The astronomy community has held the Celestron CGEM equatorial platform in high esteem for a long time. Despite its enormous popularity, Celestron saw that they could make it even better by giving it a complete renovation inside and out.

With a more ergonomic design that includes longer lock levers, the Celestron CGEM II equatorial mount provides a more convenient user experience than its predecessor. Plus, the included heavy-duty dual saddle plate fits both CGEM (Losmandy) and CG-5 (Vixen) dovetails for mounting virtually any optical tube even when an adapter is not available.

The CGEM II Series mount features an ample payload capacity of 40 pounds. Though the CGEM II is sturdy enough to take on an 11" EdgeHD OTA, it does not sacrifice any portability as it can be broken down into manageable parts for easy storage while driving to and from a nearby star party location. In addition, the mount weighs only 40 pounds by itself without the upgraded tripod or counterweights. Tripod weighs 20 pounds.

The tripod that comes with the CGEM II has 2" stainless steel legs and a spreader bar that presses against them for exceptional rigidity and support. Tripod legs also feature graduated markings that make leveling a painless procedure. In addition, eyepiece receptacles can be found at the center of the spreader. This puts any extra eyepieces you decide to bring along for your next viewing party within easy reach.

Incorporating electronics from both the previous CGEM design as well as the new CGEM II, this mount will allow you to assemble, use, and care for it using the cutting-edge features listed below:

  • Precise polar alignment on each and every star in the sky is possible with the CGEM II, even if you are unable to view the celestial pole, due to a built-in All-Star Polar Alignment program. You won't need that polar finderscope anymore!
  • Tracks beyond the meridian for flawless imaging over the ideal area of the night sky.
  • Features PPEC (Permanent Periodic Error Correction) which enables you to train out the periodic error on your worm gears only once and have the system remember your PEC recordings even after you shut the system down.
  • 5 degrees per second slewing potential for quickly taking you where you want to go!
  • The bottom of the NexStar GoTo controller features a USB 2.0 port to enable not only firmware updates for the mount and controller, but to connect directly to a PC using ASCOM compliant software as well.
  • A built-in celestial database permits up to 100 user-selected objects and allows you to investigate over 40,000 stars, planets, star clusters, nebulae, galaxies and more with merely the touch of a button! Detailed information is provided for 200 of the night sky's best objects.
