Product Description

Celestron CGX-L Equatorial Mount with 11" Schmidt Cassegrain Telescope

Celestron has paired their CGX-L equatorial mount with their 11" SC optical tube.   The perfect combination of professional level equatorial mount with a manageable optical tube allows you to take advantage of a premium mount's tracking abilities, but set up alone in the field and easily transport your system.   With a 75 pound load capacity, the CGX-L easily handles the 11" allowing you to really expand on your system without worrying about load capacities.  

About the 11" Schmidt Cassegrain Optical Tube

Weighing only 27.5 lbs., this telescope is still portable enough to be taken to dark skies, but it has 89% more light gathering power than an 8” telescope. Using an (optional) f/6.3 Focal Reducer makes it usable with a wide variety of CCD cameras. As a visual instrument you can search for all of the Messier Catalog (like beautiful M13), NGC, IC and Caldwell objects. Turn this scope to the planets and see amazing detail on the surface of Jupiter, see Cassini’s Division in the rings of Saturn, and resolve details on the surface of Mars. Even the distant Uranus, Neptune and Pluto are within your reach. 

Celestron Schmidt-Cassegrain Optical Tube Assemblies (OTA) are available individually to be used with your favorite mount. Each OTA is made to the same exacting standards as those used on all their high quality telescopes. All optical surfaces are coated with StarBright XLT coatings. 

About the CGX-L Equatorial Mount

Part of the next generation of equatorial mounts from Celestron, the CGX-L features a robust load capacity of 75 pounds with an excellent load to weight ratio.  Designed with imaging in mind, you will find additional auxiliary ports and an autoguiding port on the dec for improved cable management.   Worm gears have been upgraded to a larger (compared to previous models) 144mm gear for excellent tracking and slewing with heavy loads and smart design improvements like a longer saddle plate and 2.75" provide a highly stable and secure platform for your large aperture telescope.  

With a shorter, more compact mount head and built in handles, the CGX-L is surprisingly easy to carry and assemble.  As part of it's ergonomic design, the adjustment knobs are designed for reduced friction and a stationary latitude knob with a newly-designed linkage system greatly reduces the amount of friction when polar aligning the mount. Teflon bearings on the azimuth adjustment allow you to adjust even with a full load on the mount and an the latitude scale is large, clear and easy to read. 

CGX-L Features:

  • 75 pound load capacity
  • A shortened mount profile creates a more compact mount that is easier to carry and assemble but also improves the mounts central gravity boosting load capacity.
  • High torque motors with better slewing and tracking ability.
  • A belt driven motor minimizes backlash but remains smooth even when handling a large telescope.  A clear window allows you to easily monitor the motor.  
  • Spring loaded brass worm wheel and stainless steel worm gear.  By spring loading the motor worm and gear, gear friction is greatly reduced and optimal gear mesh is maintained. 
  • Internal cabling keeps your mount free from cable clutter and reduces the chance of snagging wiring.  The power input port and accessory ports stay in one position at all times.  
  • The CGX-L has built-in physical hard stops and optical hard stops eliminating the chance that the counterweight shaft will strike the leg.   
  • Designed for easy remote control, home sensors allow you to start in the index position no matter what position the mount was in when it was powered off. 
  • Includes a USB 2.0 Nexstar+ hand controller equipped with Celestron's PWI telescope control software designed in partnership with PlaneWave Instruments, featuring multi-point mount modeling for precision pointing accuracy. 
  • Includes Celestron's All Star Polar Alignment for incredibly accurate guided polar alignment allowing you to align with any bright fixed object in the night sky.  There's no need for additional polar finders or accessories.  
  • The head of the Celestron CGX-L is fully adjustable allowing you to slide the telescope perfectly over the center of gravity and take full advantage of the 3º-65º latitude range.
  • Includes a dual saddle plate to accommodate both D and V series dovetail plates. 
  • +20º of additional tracking past the meridian on either side
  • The 2.75" steel tripod has been newly designed for the CGX-L with a wider stance and a lower minimum height than it's predecessors.  
  • 2 autoguider ports for better cable management.  
  • PEC sensor and PPEC ready. 
  • A threaded power connector to ensure your mount never comes disconnected at the base. 
  • A red lit on/ off switch makes it easy to find in the dark. 
  • Internal Real Time Clock.
