Product Highlights

Patented Design Optimized for Imaging
400mm Focal Length/ f/2.0 Focal Ratio
StarBright XLT Optical Coating System
4-Element Rare-Earth Optical Glass

With the Advanced VX 800 200mm f/2.0 Rowe-Ackermann Schmidt Astrograph GoTo EQ Telescope, Celestron combines their purpose-built and patented catadioptric astrograph with a solid and stable motorized computer-controlled GoTo mount to give you a complete imaging rig that will allow you to capture stunning images of everything from the marias of the moon to wispy nebulae. This telescope includes a fast 8" RASA optical tube, the Advanced VX mount, a sturdy 2" stainless steel tripod, and an array of basic accessories. All you need is a camera or imaging rig and a dark sky to point it all at.

Celestron 8" f/2.0 Rowe-Ackermann Schmidt Astrograph (OTA Only)

The Celestron 8" f/2.0 Rowe-Ackermann Schmidt Astrograph (RASA) is specifically designed for astrophotography and astro-imaging with a large aperture and fast focal ratio. Using four-element rare-earth optical glass lenses ensures accurate color rendition and eliminates aberrations such as coma and field curvatures. The improved StarBright XLT multi-coating system, which includes anti-reflection coatings on the lenses and highly reflective coatings on the mirrors, increases light transmission throughout the entire optical path. An integrated fan reduces cooldown time and provides optimal airflow through the optical tube assembly (OTA) while filtering harmful dust from the interior.

The astrograph design is defined by its fast focal ratio, which reduces exposure times without sacrificing image quality and gives you more time for multiple shots of the same object for layering or with different filters. Its internal Ultra-Stable focusing mechanism enables very precise focusing to clearly resolve topographic details on the Moon or split double stars and reveal details of most other celestial objects in between, while minimizing unwanted lateral movement of the primary mirror when focusing or slewing. Since this OTA is designed as an imaging scope, a 42mm camera T-adapter and C-mount imager adapter are included that are compatible with most camera-specific T-rings that are widely available.

Optical Performance

203mm (8") diameter aperture enables near- and deep-sky viewing without being prohibitively large or heavy for easy transport to viewing locations
400mm focal length helps to produce a fast focal ratio
Fast f/2.0 focal ratio requires significantly lower exposure times versus slower ratios to produce the same results
Rowe-Ackermann Schmidt astrograph (RASA) design is purpose built for astrophotography and imaging performance, and is not recommended for visual use
Proprietary StarBright XLT fully multi-coated optical system
Four-element rare-earth glass for true color rendition without aberrations across the entire field of view
Wide 390-800nm spectral range improves images of deep space objects like galaxies and nebulae
Image circle: 22mm (0.86")
Resolution: 0.68 arcsec (Rayleigh), 0.57 arcsec (Dawes)
Back focus: 25mm (0.98") with included camera adapter, 29mm (1.14") from top of threaded collar
Optical window can be removed and replaced with optional filters such as a light pollution filter
Integrated cooling fan brings optical system to ambient air temperature for better performance
Runs on eight user-supplied AA batteries or optional 12VDC power adapter

StarBright XLT Coating System

Multi-layer mirror coatings made from layers of aluminum, SiO2 (silicon dioxide), and TiO2 (titanium dioxide)
Reflectivity is flat across the light spectrum, for both astrophotography/astro-imaging
Multi-layer anti-reflective coatings made from layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide)
High-transmission water white glass corrector lens with 97.4% light transmission

Focuser

Focusing system moves primary mirror forward and back to achieve tack-sharp images
Ultra-stable design minimizes unwanted lateral movement of the primary mirror when focusing or slewing
Fine adjustments for precise focusing, approximately 30 turns of the knob runs through the focus range

Mounting

OTA only, mount and tripod required for proper use
Includes large CGE/Losmandy-D dovetail plate for use on larger more stable mount heads
Weight: 17 pounds

Included Accessories

Standard M42 camera T-adapter accepts most camera-specific T-rings to directly mount DSLR and mirrorless cameras
CCTV/Imager C-thread adapter accepts most camera-specific video T-rings to mount imaging and video cameras
Battery pack takes eight user-supplied AA batteries to power the integrated cooling fan

Celestron Advanced VX GoTo German Equatorial Mount

Engineered and optimized for astrophotography with mid-sized optical tube assemblies (OTAs), the Celestron Advanced VX GoTo German Equatorial Mount delivers the performance required for clear images through the use of dual-axis low-cog DC servo motors and backlash compensation. Added to this are encoders on the motors and Permanent Periodic Error Correction (PPEC), which help to improve positioning and tracking precision and ensure your target object stays centered for long-exposure photography techniques. Supporting the mount is a large 2" stainless steel tripod that has a wide stance for stability on most terrain and a center tray that holds 1.25" and 2" eyepieces and accessories and acts as a leg lock to further stabilize while helping to minimize vibrations.

The brain of the system is the NexStar+ computer controller, which is equipped with a database of over 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog; it can also be programmed with up 100 custom user-defined objects with filters to create custom object lists. Its intuitive menu-driven user interface makes observing the heavens fast and easy; features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller an invaluable tool to new users and experienced stargazers alike.
