  • Celestron Advanced VX 9.25" EdgeHD Telescope

    The Celestron Advanced VX 9.25" EdgeHD Telescope combines a formidable 235mm (9.25") aplanatic optical system with the astrophotography-focused Advanced VX equatorial mount. This package delivers astrograph-quality images with its native 2350mm focal length at f/10, mounted on a GoTo platform with a 30 lb instrument load capacity. The EdgeHD optics resolve details down to a razor-sharp 0.49 arc seconds (Dawes) and gather 1127x more light than the naked eye, establishing a new standard for portable deep-sky and planetary imaging systems.

    EdgeHD Optics: A 235mm Flat-Field System for Sharp Stars

    The EdgeHD optical design produces a focal plane more than three times flatter than a standard Schmidt-Cassegrain. This aplanatic system corrects for both coma and field curvature, delivering pinpoint stars across a massive 42mm image circle. This means you can use large full-frame camera sensors and see perfectly round stars from the center of your image all the way to the corners.

    With a 235mm aperture and premium StarBright XLT coatings, the light gathering power is sufficient to resolve faint details in distant galaxies and planetary nebulae. The 0.49 arc-second Dawes resolution separates tight double stars and reveals fine detail in Jupiter's cloud bands and Saturn's rings, making it a powerful instrument for both visual observation and serious imaging.

    Three Telescopes in One: f/10, f/7, and f/2 Imaging

    The 9.25" EdgeHD is one of the most versatile optical tubes available, offering three distinct focal ratios for different imaging applications. This flexibility allows you to perfectly frame any celestial target without compromise.

    • Native f/10: The 2350mm focal length is ideal for high-resolution planetary, lunar, and solar imaging, and provides the scale needed to capture small galaxies and planetary nebulae.
    • Reduced f/7: With the optional 0.7x EdgeHD reducer lens, the telescope transforms into an f/7 system. This provides a wider field of view and cuts exposure times nearly in half, perfect for capturing larger deep-sky objects like the Orion Nebula (M42).
    • Ultra-Fast f/2: The optical tube is Fastar-compatible. By replacing the secondary mirror with an optional Starizona HyperStar lens, you can image at an incredibly fast f/2, capturing vast swaths of the night sky with extremely short exposures.

    Advanced VX Mount: 30 lb Capacity with All-Star Polar Alignment

    The Advanced VX (AVX) mount is engineered from the ground up for astrophotography. It provides a stable, portable platform with a 30 lb instrument load capacity, easily handling the 21 lb optical tube and a full imaging train. Key features like Permanently Programmable Periodic Error Correction (PPEC) and Celestron's All-Star Polar Alignment routine make it possible to achieve observatory-level tracking from any location, even without a clear view of Polaris.

    The mount head weighs just 17 lbs and is supported by a robust tripod with 2" diameter stainless steel legs. The dual CG-5/CGE saddle plate ensures compatibility with a wide range of optical tubes, making this a mount that can grow with you for years.

    NexStar+ and PWI: 40,000+ Objects & Advanced Mount Modeling

    At the heart of the AVX is the NexStar+ hand controller, which gives you access to a database of over 40,000 celestial objects. For more advanced control, the package includes a free download of Celestron's PWI Telescope Control Software. Co-developed with PlaneWave Instruments, CPWI features a graphical planetarium interface and PointXP mount modeling, allowing you to add over 100 calibration points for unmatched pointing and tracking accuracy.

    Your purchase also includes Celestron's Starry Night Special Edition Software, a powerful tool for learning about the night sky and planning your observing and imaging sessions from your PC.

    AVX 9.25" vs. 8" EdgeHD: Aperture and Portability

    When choosing an EdgeHD system on the AVX mount, the primary decision is between the 8" and 9.25" models. While both are exceptional performers, they serve slightly different priorities.

    • The 8" EdgeHD Advantage: The 8" optical tube is lighter (14 lbs), leaving more of the mount's 30 lb capacity for heavier cameras, filter wheels, and off-axis guiders. It also cools down faster and is slightly more compact, making it an excellent choice for those who prioritize portability.
    • The 9.25" EdgeHD Advantage: The 9.25" aperture provides a 33% increase in light-gathering ability over the 8" model. This translates directly to brighter images and shorter exposure times. Its longer 2350mm focal length also delivers a larger image scale, which is critical for resolving finer details on planets and capturing smaller deep-sky objects. For many, the 9.25" is the "sweet spot" in Celestron's lineup, offering a significant jump in optical power while remaining manageable on the portable AVX mount.
  • Is the 30 lb capacity of the Advanced VX mount enough for the 9.25" EdgeHD for astrophotography?

    Yes. The 9.25" EdgeHD optical tube weighs 21 lbs, leaving 9 lbs of capacity for your camera, finderscope, and other accessories. This is a well-matched combination for deep-sky imaging, provided the system is properly balanced.

    What size camera sensor can the Celestron 9.25" EdgeHD fully illuminate?

    The Celestron 9.25" EdgeHD is designed with a 42mm image circle. This is large enough to fully illuminate full-frame sensors (36mm x 24mm) without vignetting, making it an excellent choice for imagers using DSLR, mirrorless, or dedicated astronomy cameras with large sensors.

    How do I convert the 9.25" EdgeHD to an f/2 imaging system?

    This telescope is Fastar-compatible. To image at f/2, you must purchase an optional Starizona HyperStar lens. The conversion involves carefully unthreading the secondary mirror from the corrector plate and threading the HyperStar lens in its place. This transforms the telescope into an incredibly fast, wide-field astrograph.

    What kind of detail can I expect on Jupiter with the AVX 9.25" EdgeHD?

    Under good seeing conditions, the 2350mm focal length and 0.49 arc-second resolution of the 9.25" EdgeHD will allow you to clearly resolve Jupiter's main cloud bands, the Great Red Spot, and the shadows of the Galilean moons as they transit the planet's disk. With a high-speed planetary camera, you can capture incredibly detailed images.

    Is the Advanced VX 9.25" EdgeHD good for imaging galaxies like the Whirlpool Galaxy (M51)?

    Absolutely. The 2350mm focal length at f/10 provides the ideal image scale for framing medium-sized galaxies like M51, allowing you to capture detail in the spiral arms. The flat field of the EdgeHD optics ensures that stars in the surrounding field remain sharp and not distorted by coma.

    Do I need to see Polaris to polar align the Advanced VX mount?

    No. The mount includes Celestron’s All-Star Polar Alignment procedure. This allows you to use any bright star in the sky to achieve an accurate polar alignment, making it easy to set up in locations with an obstructed northern (or southern) horizon.
