All you need is to simply attach your camera and you'll be taking spectacular astrophotography of wide-field deep sky objects in no time. Despite being the same size as the CGEM II, Celestron's CGX is a big step up in performance and features, especially for imaging applications.    RASA Performance Made for Everyone Capture spectacular wide-field deep sky images in seconds with Celestron’s new portable astrograph - the CGX Equatorial 800 RASA Telescope! This incredibly fast f/2.0 system is the perfect companion to today’s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras, and allows you to produce sharp, detailed images (skipping the autoguider completely in many cases). Furthermore, it's convenient and easy to transport at just under 8kg. Note that the 8" RASA is purely designed for imaging and cannot be used visually. The latest addition to the RASA family, this 8” version is a much more portable and affordable version of the famous RASA 11. It delivers the same quality flat field without optical abberations, allowing you to capture stunning deep-sky astronomical images without the difficulties of longer focal length instruments, doing so at a much lower cost! It has many of the same thoughtfully designed features as its “big brother” RASA 11, including the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar.   Shorter Exposure Times and Virtual “Real-Time” Observing Since it is an f/2.0 optical system, imagers can use shorter exposure times to capture detail in faint objects. When combined with sensitive cameras and the proper “live stacking” software, the 8” RASA can provide an almost real-time observing experience. The RASA will show images on a computer instantly that are brighter and more detailed than those using much bigger telescopes with the naked eye.   Ultra-Stable Focus System Focusing is easier, more accurate, and more stable than ever! Celestron unveiled a new focuser design that mitigates lateral movement of the primary mirror when focusing or tracking. The key to their ultra stable focus system is two sets of precision bearings that are precisely aligned (and individually tested during assembly) to ensure perfect results.   Built for Today’s Latest Cameras Unlike the larger RASAs that are designed specifically for DSLR and large CCD cameras, the 8” RASA was specifically created with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does NOT work with standard DSLR cameras. It is optimized for sensors with up to a 22mm diagonal, and performs well with sensors up to 32mm diagonal. The APS-C sized sensors used in many mirrorless cameras are a good choice. 42mm full frame sensors will also work, but performance will be poor at the edges of the sensor and field illumination will be reduced. Additionally, we do not recommend pairing RASA 8 with any camera body more than 4” in diameter.   Camera Compatibility Camera Compatible with RASA 8?

Unlike many telescopes that only perform well over the visible spectrum (400-700nm), the 8” RASA’s optics are designed to perform over a wider spectral range, from 390-800nm. This allows more of the light emitted from the astronomical object to be sharply focused in the image. Celestron's engineers designed the RASA with a removeable optical window, so you can maintain peak optical performance if a filter is added or if a camera has its own optical window. Celestron offers a Light Pollution Imaging Filter designed specifically for the 8” RASA, which mounts in place of the optical window. All refractive optical surfaces are coated with StarBright XLT coatings, whilethe primary mirror uses enhanced aluminum coatings. This maintains high light transmission through the entire optical system.   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   Compatible With     Full Specifications Optical Tube Assembly (OTA) Optical Design Rowe-Ackermann Schmidt Astrograph (RASA) Aperture 203mm (8-inches) Focal Length 400mm (15.74-inches) Focal Ratio f/2.0 Light Gathering Power (Compared to Human Eye) 843x Resolution (Rayleigh) 0.68 Arc Seconds Resolution (Dawes) 0.57 Arc Seconds Image Circle 22mm (.86") Ø, 3.15° Usable Field 32mm (1.26") Ø, 4.6°Only Minimal Performance Loss at Edge of FOV Wavelength Range 400 - 800nm Spot Size < 4.6 μm RMS Across Image Circle Central Obstruction 93mm (3.66") Central Obstruction by Diameter 46% Optical Coatings StarBright XLT Off-Axis Illumination 93% at 11mm (.43") Off-Axis Optical Window 46mm (1.81") Ø Back Focus with Included Camera Adapter 25mm (0.98") Back Focus from Top of Threaded Collar 29mm (1.14") Focuser Ultra-Stable Focusing System (USFS) Other Features Air-Cooling SystemIntegrated Filter Mount Optical Tube Construction Aluminium Optical Tube Length 628mm (24.7") Optical Tube Diameter 235mm (9.3") Optical Tube Weight 7.7kg 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 56.3kg Warranty Celestron 2 Year Warranty   Recommended Accessories Celestron StarSense AutoAlign AccessoryAutomatically align your telescope in moments!
