This fast, wide-field f/2.2 system offers two huge advantages over traditional f/10 for astrophotography: better apparent tracking and shorter exposures. This means that you’ll be able to create better-looking astroimages in a shorter time period, even without the use of an autoguider. With today's CCD sensor sizes as large as film,the RASA offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. Combined with a focal length of 620mm, the RASA is your must-have instrument for wide-field imaging, surveying, comet hunting, and creating beautiful mosaics of the night sky.   Optical Performance The Rowe-Ackermann Schmidt Astrograph features newly designed optics with 4-element rare-earth glass for images without false colour and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle is unprecedented for an astrograph in this price range—or even that of a much more expensive instrument. The design also provides minimal vignetting.   Advanced Features Custom engineered linear brass focuser bearings and FeatherTouch Micro Focus Knob allow you to make the fine adjustments needed to capture the perfect shot, while a 12V MagLev fan reduces cool down time and provides optimal airflow through the dust filtered optical tube. Engineered as a complete astroimaging system, every component of the RASA is optimized for peak performance with DSLR and astronomical CCD cameras. Every assembly piece, down to the thickness of the glass used in the included fully-multicoated optical window or an optional imaging filter has been taken into careful consideration to work together seamlessly.   RASA (Rowe-Ackermann Schmidt Astrograph) Features Ultra-fast, 11" f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature; Cuts imaging time by more than half Expansive 43.3 optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52mm for larger format sensors. Custom engineered linear brass focuser bearing reduces image shift, while dual-speed 10:1 FeatherTouch Micro Focus Knob provides the most precise focusing Quiet, high-output 12V MagLev fan reduces cooldown time and blocks dust Common camera adapters (T-thread and M48) included for easy attachment to popular CCD and DSLR cameras   CGX Mount and Tripod Features 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   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 Tube Assembly (OTA) Optical Design Rowe-Ackermann Schmidt Astrograph (RASA) Aperture 279mm (11-inches) Focal Length 620mm (24.4-inches) Focal Ratio f/2.2 Light Gathering Power (Compared to Human Eye) 1588x Resolution (Rayleigh) 0.49 Arc Seconds Resolution (Dawes) 0.41 Arc Seconds Image Circle 43.3mm (1.7") Ø, 4.0° Usable Field 52mm (2.04") Ø , 4.8°Only Minimal Performance Loss at Edge of FOV Wavelength Range 400 - 700nm Spot Size < 4.4 μm RMS Across Image Circle Central Obstruction 114mm (4.48") Central Obstruction by Diameter 41% Optical Coatings StarBright XLT Off-Axis Illumination 83% at 21mm (0.82") Off-Axis Optical Window 68mm (2.67") Ø Back Focus with Included Camera Adapter 55mm (2.16") Back Focus from Top of Threaded Collar 72.8mm (2.86") Focuser Ultra-Stable Focusing System (USFS) Other Features Air-Cooling SystemIntegrated Filter Mount Optical Tube Construction Aluminium Optical Tube Length 838.2mm (33") Optical Tube Diameter 330.2mm (13") Optical Tube Weight 19.5kg Dovetail CGE Dovetail Bar Computerised Mount Mount Type Computerised Equatorial (EQ) Payload Capacity 25kg Tripod Material Stainless Steel Height Adjustment Range (Including Mount and Tripod) 1200.15 - 1968.5mm Tripod Leg Diameter 50.8mm (2") Tripod Weight 8.7kg Accessory Tray Yes Mount Head Weight 20kg Slew Speeds 9 Slew Speds (Max Speed 4° / Second) Tracking Rates Sidereal, Solar and Lunar Tracking Modes EQ North, EQ South GPS N/A Dovetail Compatibility Dual Saddle Plates (CG-5 / CGE) Auxiliary Ports 2 Aux Ports Autoguide Port Yes USB Port Yes (Hand Controller Input) Power Reqiurements 12V DC 4A (Tip Positive) 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 Controller Double Line, 18 Character Liquid Crystal Display; 19 Fiber Optic Backlit LED Buttons and USB 2.0 Port for PC Connection NexStar+ Database 40,000+ Objects with 100 User Defined Programmable Objects and Enhanced Information on Over 200 Objects Software CPWI Telescope Control Software, Celestron Starry Night Special Edition Software, SkyPortal App Total Kit Weight 68kg Warranty Celestron 2 Year Warranty   Recommended Accessories Celestron StarSense AutoAlign AccessoryAutomatically align your telescope in moments!
