With over 9" aperutre and Celestron's premium StarBright XLT coatings, a CGX 925 HD gives you over 1000 times the light gathering power than the unaided eye. Designed to give diffraction limited performance and offer more resolution than the 800 with less weight than the 1100, the CGX 925 HD is a premier astroimaging telescope made for remote operation.   See the Universe in HD | True Astrograph Quality EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce off-axis star coma and provide an astrograph-quality flat focal plane all the way to the edge of the field of view. Experience amazing optical performance with EdgeHD’s flat-field and coma-free optics for pinpoint stars all the way to the edge of today’s largest imaging sensors and widest eyepieces Aluminum optical tube with tube vents featuring an integrated 95-micron mesh filter 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 3 focal ratios: native f/10, f/7 with the addition of a focal reducer, or ultra-fast f/2 imaging with a removable secondary mirror and third-party accessories   CGX Mount and Tripod Features | Improved Performance The new CGX was designed to better support your telescope for both visual and astro-imaging pursuits. It is Celestron's new equatorial backbone to support a wide range of telescopes. Sturdier and more rigid with quicker dampening time Increased load capacity to 25kg Improved motors provide more torque, better slewing and tracking under heavy loads Heavy duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads 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 accessory ports remain stationary while the mount slews to avoid snags Internal hard stops for both axes prevents 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 Brand new control software developed for professional level control operation and imaging Software includes multi-point mount modeling for extremely precise pointing accuracy and many more additional features for remote astroimaging Wider tripod stance for improved stability Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3°-65° latitude range Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle   Improved Tripod Includes 2" steel legs with height index marks for quick leveling "Jack of all trays" to hold three 1.25" eyepieces, two 2" eyepieces, your smartphone, or other accessories +20° of additional tracking past the meridian on either side Tripod legs can be collapsed with accessory tray installed for faster setup and transport   Mechanical Features Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor). Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in. Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.   Improved Ergonomics Two handles for easy pickup and transport 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  Optional add-on polar axis finderscope   Electronics NexStar+ hand control with USB port Two AUX accessory ports to support wireless/WiFi alignment and operation with StarSense AutoAlign and SkyPortal WiFi Module accessories (sold separately) USB 2.0 port, used to connect directly to PC with included software Autoguider port PPEC ready Threaded 12VDC power input barrel connector Internal Real Time Clock (keeps time and site information saved   Compatible With     Full Specifications Optical Design EdgeHD Aperture  235mm (9.25") Focal Length 2350mm (93") Focal Ratio f/10 Focal Length of Eyepiece 1 23mm (0.91") Magnification of Eyepiece 1 102x Finderscope 9x50 Star Diagonal 2" with 1.25" adapter Optical Tube Aluminium Highest Useful Magnification 555x Lowest Useful Magnification 34x Limiting Stellar Magnitude 14.4 Resolution (Rayleigh) 0.59 arc seconds Resolution (Dawes) 0.49 arc seconds Secondary Mirror Obstruction 85mm (3.35") Optical Coatings StarBright XLT Optical Tube Length 559mm (22") Optical Tube Diameter 271.78mm (10.7") Optical Tube Weight 9.53kg Dovetail CGE Dovetail Bar   Mount Info: Mount Type Computerised Equatorial Instrument Load Capacity 25kg Height adjustment range (includes mount and tripod) 1200.15mm - 1968.5mm Tripod Leg Diameter 50.8mm  Latitude adjustment range 3° - 65° Mount Head Weight 20kg Accessory Tray Yes Tripod Weight 8.7kg Weight of Counterweights 2 x 11lbs (5kg) Slew Speeds 9 slew speeds - max speed 4°/second Tracking Rates Sidereal, Solar, and Lunar Tracking Modes EQ North & EQ South GPS N/A Dovetail Compatibility Dual saddle plates (Vixen and CGE saddle) Auxiliary ports 2 Aux ports (Hand Control can use either Aux port) Autoguide port Yes USB Port 1 port (for Mount and Hand Control) Power Requirements 12V DC, 4 amps Motor Drive DC servo motors Alignment Procedures 2-Star Align 1-Star Align Solar System Align Last Alignment Quick Align Periodic Error Correction Yes Computerised Hand Control Double line, 18 character Liquid Crystal Display; 19 fiber optic backlit LED buttons, USB 2.0 port for PC connection NexStar+ Database 40,000+ objects 100 user defined programmable objects  Enhanced information on over 200 objects Software PWI Telescope Control Software Celestron's Starry Night Special Edition Software SkyPortal App Included Items CGX Equatorial Head CGX Tripod Accessory Tray 2 x 11 lbs (5kg) counterweights  NexStar+ Hand Control 8mm Allen wrench 12V DC Power Cable Hand Control Holster   Recommended Accessories Celestron StarSense AutoAlign AccessoryAutomatically align your telescope in moments!
