DescriptionExperience the pinnacle of celestial imaging with the Celestron Advanced VX800 8" Rowe-Ackermann Schmidt Astroscope (RASA), a powerful and innovative telescope designed for the modern astrophotographer. This advanced astrograph system pairs the high-quality 8" RASA with the robust and portable Advanced VX German equatorial mount, creating an unparalleled stargazing package that\'s ready for your mirrorless camera to capture the cosmos in stunning detail.The 8" RASA is a marvel of optical engineering, featuring a fast f/2.0 focal ratio and a patented optical design that eliminates the need for an autoguider in many situations. Its large 8-inch aperture allows for an influx of light, ensuring that your images are bright and clear, with razor-sharp stars across a wide field of view. The telescope\'s flat field without optical aberrations provides exceptional contrast and resolution, allowing you to observe celestial wonders with more detail than ever before.Weighing just 17 pounds, the 8" RASA is not only powerful but also highly portable, making it easy to transport to remote dark sky locations. Its shorter 400mm focal length reduces the demands on equatorial tracking, allowing for shorter exposure times and the potential for virtual "real-time" observing when paired with the appropriate live stacking software and sensitive cameras.Celestron\'s Ultra-Stable Focus System is a standout feature, incorporating precision bearings to ensure minimal lateral movement of the primary mirror, resulting in easier and more accurate focusing. This system is a testament to Celestron\'s commitment to providing durable and reliable equipment for serious astronomers.Designed with today\'s technology in mind, the 8" RASA is optimized for use with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. It is specifically tailored for sensors up to a 22mm diagonal but can also accommodate sensors as large as 32mm diagonal. The telescope\'s compatibility with APS-C sized sensors and 42mm full-frame sensors, although with some limitations at the edges, makes it a versatile choice for a variety of camera setups.The Advanced VX mount, included in this package, is a testament to Celestron\'s innovative technology. It features All-Star Polar Alignment, Celestron PWI telescope control software, SkyAlign, and permanently programmable periodic error correction (PPEC). Whether you\'re a seasoned imager or a newcomer to the field, the Advanced VX mount provides a user-friendly experience with its computerized GoTo capability and sturdy 2" diameter steel tripod legs, ensuring stability and a payload capacity of 30 lbs.To enhance your astronomical journey, Celestron includes the Celestron PWI Telescope Control Software, co-developed with PlaneWave Instruments, offering an advanced graphical planetarium interface and comprehensive ASCOM telescope interface. Additionally, your purchase grants you access to a free download of Celestron\'s Starry Night Special Edition Software, which provides a wealth of information about celestial objects and assists in planning your observing or imaging sessions.The Celestron Advanced VX800 8" RASA Telescope is not just an instrument; it\'s a gateway to the stars, providing a sophisticated and seamless experience for capturing the universe\'s most awe-inspiring phenomena. Whether you\'re looking to delve into deep-sky imaging or enjoy the thrills of near real-time observation, this telescope is the perfect companion for your astronomical adventures.FeaturesRowe-Ackermann Schmidt Optical Design - 8" f/2.2 flat field imaging system with rare-earth glass for outstanding images free of optical defects like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.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 astrograph does not work with standard DSLR cameras.Ultra-Stable Focus System - six precision sealed ball bearings virtually eliminate image shift.Integrated air-cooling system - 12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.Internal filter mount - seamlessly accommodates a Light Pollution Imaging Filter into the optical path.Performs over a wider spectral range than most telescopes, from 390-800 nm, so more of the light passing through the astrograph is in sharp focus.Advanced VX, the most compact and portable of Celestron\'s German equatorial mounts, offers a maximum instrument capacity of 30 lb with the same rigidity as our larger mounts and minimal flexure.This mount offers every feature an astroimager wants: PEC, an autoguider port, the ability to image across the meridian, and more.NEW dual saddle plate accommodates both the narrow CG-5 and larger CGE dovetail.Accessories included: M42 camera adapter, C-thread camera adapter, and fan battery pack.SpecificationsOptical DesignRowe-Ackermann Schmidt AstrographAperture203mm (8")Focal Length400mm (15.74")Focal Ratiof/2.0Central Obstruction Diameter93mm (3.66") (46% of aperture diameter)Light Gathering Power843xResolution (Rayleigh)0.68 arc secondsResolution (Dawes)0.57 arc secondsImage Circle22mm (.86") ½, 3.15½Useable field32mm (1.26") ½, 4.6½, only minimal performance loss at edge of FOVWavelength range390 - 800 nmSpot size< 4.6 ½m RMS across image circleOptical CoatingsStarBright XLTOff-axis Illumination93% at 11mm (.43") off-axisOptical Window46mm (1.81")Back focus with included camera adapter25mm (.98")Back focus from top of threaded collar29mm (1.14")Optical TubeAluminumOptical Tube Length628mm (24.7")Optical Tube Diameter235mm (9.3")FocuserUltra-Stable Focusing SystemDovetailCGE Dovetail BarMount TypeComputerized EquatorialInstrument load capacity30 lbs (13.6 kg)Height adjustment rangeincludes mount and tripod)
