Ready to see the moon and more? Become an expert in astronomy today. The Celestron EdgeHD is an aplanatic flat-field Schmidt optical system designed to produce aberration-free images with pinpoint stars all the way to the edge of the field of view of today’s largest imaging sensors and wide field eyepieces. EdgeHD virtually eliminates both field curvature and off-axis star coma with many more features available.

Celestron EdgeHD 11-Inch Optical Tube Assembly

Celestron EdgeHD 11-Inch Optical Tube Assembly has a premium StarBright XLT coatings that provides maximum light transmission and a 9x50 finderscope, 2-Inch mirror diagonal for more comfortable viewing, and wide-angle 23 mm Luminos 2-Inch eyepiece which is designed to produce aberration-free images.

CGX-L Equatorial Mount and Tripod

The Mount holds a 75 lb load capacity. It contains 144 mm diameter worm wheels that are constructed with spring-loaded brass worm wheel and stainless steel worm gear that reduce friction and provide optimum gear mesh for heavier loads. The longer 270 mm dovetail saddle accepts both the wide, Losmandy/CGE style and the narrower Vixen/CG-5 style dovetails.

Motor

Clear windows built into motor covers so pulleys and belts can be monitored. Improved motors provide more torque and tracking under heavy loads and the heavy duty belt-drive system minimizes backlash while providing smooth motor operation at full capacity. The mount has internal cabling for worry-free remote operation. Power input and lower accessory ports remain stationary while the mount slews to avoid snags.

Internal Sensors

There are two internal optical sensors. The Home sensor allows the mount to always start in the index position regardless of orientation before a power reset and the Limit sensor automatically shuts off slewing or tracking before reaching the hard stop fail safe. The internal hard stops for both axes prevent cable tension and tripod strike.

New Software

The mount includes Celestron's PWI telescope control software, co-developed by PlaneWave Instruments. Software features an All-Star Polar Alignment allowing for quick and precise polar alignment. Align on any bright named star without extra polar alignment accessories, apps, or other assistance with the new PWI telescope control software.

Electronics

The mount comes with additional Aux accessory ports and autoguider ports on the Dec axis. NexStar+ hand control with USB port tells you much about the night sky with a press of a button. The USB 2.0 port is used to connect directly to the PC with PWI Software. The PEC sensor and PPEC ready are also present. There is a threaded 12VDC power input barrel connector for added comfort and an Internal Real Time Clock which saves time and site information. The mount also has an On/Off rocker switch with a red LED. The Mount supports WiFi and wireless operation accessories which are sold separately.

Stainless Steel Tripod Legs

The 70mm stainless steel tripod legs have a wider stance for improved stability under heavy loads. Tripod legs can be collapsed with accessory tray installed for faster setup and transport. The new accessory tray holds three 1.25 and two 2 eyepieces with an upright stand for your smartphone or tablet.
