  • 1Description

Celestron provides a complete astronomical observation platform, including their updated heavy-duty mount, with the CGX EQ 800 EdgeHD 8" f/10 Schmidt-Cassegrain GoTo Telescope. This rig comes with everything you need to start making detailed observations of the Moon and planets, and deep-sky objects such as galaxies, nebulae, clusters, and stars. It comes with a large-aperture Schmidt-Cassegrain OTA, the NexStar+ computer controller, the CGEMII motorized EQ mount, a 1.25" 40mm eyepiece that produces 51x, a 1.25" 90° diagonal, and a large 2" leg-diameter stainless steel tripod.

  • EdgeHD 8 Optical Tube Assembly

    The EdgeHD 8 Optical Tube Assembly from Celestron features an Aplanatic Schmidt-Cassegrain optical system. This compound, or catadioptric, light-path employs a combination of mirrors and lenses that offer a large high-resolution aperture, a shorter tube length, and enhanced portability. This telescope has an 8.0" aperture, a focal length of 2032mm, and a focal ratio of f/10.

    The EdgeHD optical system consists of a zero power corrector plate, a spherical primary mirror, and a secondary mirror along with a set of field flattening lenses integrated into the baffle tube. The optics of an EdgeHD telescopes feature StarBright XLT multi-layer coatings on the primary and secondary mirrors for increased reflectivity. The corrector is also fully coated to ensure enhanced anti-reflection characteristics.

    The EdgeHD optical system is designed to optimize an image circle with a 42 mm diameter around the center of the field of view. This circle completely covers the diagonal of a full-frame DSLR camera or a standard 35mm film frame. As such, it extends significantly beyond the diagonal of APS-C sensors and the smaller chips used in specialized astrophotography CCD cameras. Further refinement of the system's imaging capabilities is managed via mirror tension clutches that help support the primary mirror and minimize its lateral movement. This enhancement is particularly important to astrophotographers as it significantly improves the system's stability and imaging clarity.

    This OTA comes with a very useful 9x50 finderscope fitted to its exterior. Due to its wider field of view, this ancillary optic can offer assistance in locating objects to view with the main scope.

    Normal image orientation for the EdgeHD design is upside-down and reversed. The 1.25" diagonal inverts this image so it is right-side-up, but reversed. This diagonal directly accepts 1.25" eyepieces.

    Also included in this package is Celestron's Axiom LX 23 mm wide angle eyepiece. This ocular is ideal for deep-space viewing - its wide field of view produces a feeling of being surrounded by the viewing experience.

  • CGX GoTo EQ Mount with Tripod

    Celestron's CGX GoTo EQ Mount with Tripod improves on their venerable CGEM platform to provide users with a heavy-duty research-quality mount for larger OTAs, accessories, and imaging rigs. Engineered to carry a 55-pound payload, and outfitted with high-torque motors with a heavy-duty belt drive system to improve tracking stability and reduce backlash, it is able to smoothly and accurately track near and deep-sky objects for long periods of time. Its Vixen/Losmandy dual dovetail saddle makes the mount compatible with most plates in-use today. To provide a stable platform for the mount and your OTA, a heavy-duty stainless steel tripod is included that sports large 2" diameter legs, an accessory tray that doubles as a stabilizer, and an adjustment range from 47.25 to 77.5" including the head.

    The brains of the CGX EQ is the NexStar+ computer controller. Equipped with a database of 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog, it can also be programmed with up to 100 custom user-defined objects and filters for custom object lists. Its intuitive menu-driven user interface allows you to observe the heavens with nine slew speeds and three tracking rates, plus anti-backlash compensation and Permanent Periodic Error Correction (PPEC) for smoother movements in the motors, and improved tracking over time. Features, such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller easy to use and invaluable to new users and experienced star-gazers.
