Celestron Advanced VX 8 EdgeHD

Full review

The Celestron Advanced VX 8 EdgeHD pairs an 8-inch aperture Schmidt-Cassegrain optical tube with Celestron's proven Advanced VX equatorial mount, delivering a serious step up for amateur astronomers ready to move beyond entry-level gear. The EdgeHD optical design uses aplanatic optics to eliminate coma and field curvature, producing pinpoint stars across the entire field of view rather than just at the center. This makes the instrument equally capable for detailed visual observation of planets, lunar terrain, and deep-sky objects like galaxies and nebulae, as well as for long-exposure astrophotography, where edge-to-edge sharpness truly matters. With 2032mm of focal length at f/10, the optical tube gathers enough light to reveal faint, distant targets while still offering the versatility to be reduced for wider-field imaging with an optional focal reducer.

The Advanced VX mount underneath is a fully computerized German equatorial design built to carry the 8-inch EdgeHD tube with stability to spare, even during windy nights or when a guide camera and other accessories are attached. Its permanent periodic error correction (PEC) and All-Star polar alignment routine make it straightforward to achieve the precise polar alignment necessary for tracking and imaging, without needing to see Polaris directly. The mount's database contains over 40,000 celestial objects, and its GoTo system slews to targets quickly and accurately once aligned, a feature that saves considerable time during a session and helps observers actually spend their night looking through the eyepiece instead of hunting for objects manually. Sturdy stainless steel legs on the tripod, along with a redesigned mount head with improved cabling and structural rigidity compared to earlier Celestron mounts, contribute to the steadiness required for high-magnification planetary views and deep-sky imaging alike.

Rounding out the package are practical touches that reflect Celestron's experience serving both visual and imaging astronomers: a StarBright XLT fully multi-coated optical system for maximum light transmission, a two-inch primary mirror lock to reduce image shift when focusing, and compatibility with Celestron's broader ecosystem of accessories, including off-axis guiders, focal reducers, and the SkyPortal app for wireless control via smartphone. The rear cell features a stepped construction, common to EdgeHD tubes, that provides multiple back-focus distances for connecting cameras or accessories precisely where needed. Whether used from a backyard for casual stargazing or set up at a dark-sky site for a night of dedicated astrophotography, the Celestron Advanced VX 8 EdgeHD offers the optical precision, mechanical stability, and computerized convenience that make it a genuinely capable instrument for astronomers looking to grow their skills and their views of the night sky.
