- Sleek aluminum optical tube with tube vents featuring an integrated 95-micron mesh filter that allows hot air to be released from behind the primary mirror. Sturdy mirror support knobs hold the mirror in place and reduce image shifts during imaging
- Versatile design accommodates 2 focal ratios: native f/10 or ultra-fast f/2 imaging with a removable secondary mirror and third-party accessories
New CGX-L Features
- Increased 34kg load capacity; Exceptional load capacity to weight ratio
- Additional aux accessory ports and autoguider port on the dec axis for a better cable management system
- Larger 144mm diameter worm wheels that provide smoother viewing operation and drive heavier loads more accurately
- Longer 270mm dovetail saddle that support larger optical tubes easily
- Massive 70 mm stainless steel tripod legs with a wider stance for improved stability under heavy loads
- New accessory tray holds three 1.25” and two 2” eyepieces with an upright stand for your smartphone or tablet
- Heavy duty, 31.5 mm stainless steel counterweight shaft to support additional counterweights
- Optional add-on polar axis finderscope custom designed for CGX and CGX-L
- Supports WiFi and wireless operation accessories such as StarSense AutoAlign and SkyPortal Wi-Fi Module (sold separately)
Mount Features
- Compact, lower-profile equatorial head provides improved stability and portability; Sturdier and more rigid with quicker dampening time
- Improved motors provide more torque, better slewing and tracking under heavy loads
- Heavy duty belt-drive system minimizes backlash while providing smooth motor operation at full capacity
- Clear windows built into motor covers so pulleys and belts can be monitored
- Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh
- Internal cabling for worry-free remote operation. Power input and lower accessory ports remain stationary while the mount slews to avoid snags
- Internal hard stops for both axes prevent cable tension and tripod strike
- Internal optical sensors on both axes for simple and safe remote operation
- Home sensors allow the mount to always start in the index position regardless of orientation before a power reset
- Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe
- Includes Celestron's new PWI telescope control software that features multi-point mount modeling for extremely precise pointing accuracy
- Software Polar Align: “All-Star Polar Alignment” allows quick and very precise polar alignment. Align on any bright named star without extra polar alignment accessories, apps, or other assistance
- Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3°-65° latitude range
- Dual-fit Vixen/CG-5 and Losmandy/CGE dovetail saddle
- +20° of additional tracking past the meridian on either side
- Redesigned tripod has a widened stance for added stability. The minimum tripod height has also been lowered per user feedback
- Tripod legs can be collapsed with accessory tray installed for faster setup and transport
Improved Ergonomics
- Integrated handles for easy transport and portability
- New ergonomically designed dovetail clamping knobs
- Innovative and improved polar alignment adjustment system
- All-new ergonomic adjustment knobs with reduced friction for smooth and easy positioning under full loads. Stationary latitude knob with a newly-designed linkage system greatly reduces the amount of friction when polar aligning the mount. Redesigned azimuth adjustment with low-friction Teflon bearings to make adjustments easy under full load. No more binding, rough adjustments!
- Easy to read latitude scale
Electronics
- NexStar+ hand control with USB port
- USB 2.0 port used to connect directly to PC with PWI Software
- 2 available autoguider ports for optimum cable management
- PEC sensor and PPEC ready
- Threaded 12VDC power input barrel connector
- Internal Real Time Clock (keeps time and site information saved)
- On/Off rocker switch with red LED
