Celestron Advanced VX 800 RASA - Rowe-Ackermann Schmidt Astrograph - Telescope 8in f/2.0 843x 9.3in Tube

Celestron Advanced VX 800 RASA - Rowe-Ackermann Schmidt Astrograph - Telescope 8in f/2.0 843x 9.3in Tube. Simply add a mirrorless camera and this package offers everything you need to take spectacular images of wide-field deep sky objects. Capture spectacular wide-field deep sky images in seconds with Celestrons new portable astrograph the 8 Rowe-Ackermann Schmidt Astrograph (RASA). This incredibly fast f/2.0 system is the perfect companion to todays color astronomical CMOS cameras smaller CCD cameras and mirrorless cameras. Thanks to its fast focal ratio and patented optical design you can produce sharp detailed images and in many cases skip the autoguider completely. Weighing in at just 17 pounds its easy to transport your 8 RASA to the most remote dark sky locations. The 8 RASA is an imaging telescope that delivers a flat field without optical aberrations for razor sharp stars across a wide field of view. It can capture stunning deep-sky astronomical images without the challenges typically presented by longer focal length instruments at a fraction of the cost of those systems. The latest addition to the RASA family this 8 version is a much more portable and affordable version of the heralded RASA 11 which was introduced to much acclaim in 2014. With the 8 RASA joining the lineup a wider range of astroimagers can enjoy the benefits of the RASA design. 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. Purely designed for imaging the 8 RASA cannot be used visually. The prime focus focal plane is located at the front of the optical system so it cannot accommodate a traditional eyepiece. 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. View images on a computer instantly that are brighter and more detailed than can be seen in much bigger telescopes with the naked eye. Because shorter exposure times are possible your equatorial mount wont need to accurately track over extended periods. The 8 RASAs relatively short 400mm focal length also lessens equatorial tracking demands. In many cases autoguiding will not be required. Weighing only 17 lb this optical tube pairs perfectly with a wide variety of mounts. With the launch of the 8 RASA Celestron is unveiling a new focuser design that mitigates lateral movement of the primary mirror when focusing slewing or tracking with the astrograph. Focusing is easier more accurate and more stable than ever. The key to the Ultra-Stable Focus System is two sets of precision bearings that are precisely aligned and tested during assembly to ensure optimal results. Unlike the larger RASAs that work with DSLR and large CCD cameras the 8 model was designed 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 but 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. See the chart below to determine if your camera is compatible with RASA 8. The Advanced VX mount is designed to provide superior performance for smaller telescopes while taking advantage of Celestrons most advanced technologies: All-Star Polar Alignment Celestron PWI telescope control software SkyAlign and permanently programmable periodic error correction (PPEC). If youre an experienced imager youll love taking this portable mount to a dark sky site and enjoying all the conveniences of a larger observatory mount. Or if youre new to imaging Advanced VX will help you get started with the hobby and keep up with your needs for years to come. The Advanced VX is the smallest of Celestrons German equatorial mounts. The computerized GoTo capability automatically tracks objects as they move across the night sky. The Advanced VX mount includes ports for a hand control an autoguider and 2 AUX ports for optional accessories. The NexStar+ hand control gives you instant access to all the functions your mount has to offer. With automatic slewing and menu descriptions astronomers of all skill levels can master this mount in just a few observing sessions. The Advanced VX also has an impressive tripod for its class with 2-diameter steel tripod legs providing an extra-wide stance for improved stability. The payload capacity for the Advanced VX is 30 lb. It offers a sturdy platform for the 8 Rowe-Ackermann Schmidt Astrograph optical tube even when paired with optional
