Overview

The Celestron Advanced VX 8" EdgeHD is built around two things: sharp, flat-field optics and a capable equatorial mount. The 203mm aperture at f/10 gives you enough light-gathering power for detailed planetary views and deep-sky imaging, while the EdgeHD optical design corrects coma and field curvature across the full image circle, something standard Schmidt-Cassegrains struggle with at the edges. That matters most if you are attaching a camera with a large sensor.

The Advanced VX mount handles payloads up to 30 pounds, which gives you room to add a guide scope and camera without overloading the system. GoTo and tracking are included, along with an autoguider port and permanent periodic error correction, so the mount is genuinely ready for long-exposure astrophotography without major upgrades. One honest note: at 38.5kg total, this is not a grab-and-go setup.

Setup time and portability are real considerations. The Amazon rating of 3.8 out of 5 also suggests some buyers have encountered quality control variability, so inspecting your unit carefully on arrival is worthwhile. At $2,799, this is a serious investment best suited to someone committed to astrophotography.

Key Features

  • EdgeHD optics deliver a flat focal plane, which reduces star distortion toward image edges compared to standard SCT designs
  • Three usable focal ratios, f/10 native, f/7 with an optional reducer, and f/2 with Hyperstar, give flexibility for different imaging targets
  • Autoguider port and permanent periodic error correction support unattended long-exposure imaging sessions
  • All-Star Polar Alignment simplifies polar alignment without needing a clear view of Polaris
  • Dual dovetail saddle accepts both CG-5 and CGE style dovetail bars, allowing you to swap optical tubes as your needs change
  • GoTo computerized mount with tracking reduces the learning curve for finding and following objects across the sky
  • At 30 pounds payload capacity, the mount has enough headroom for a camera, guide scope, and accessories without being pushed to its limit

Excellent mount and telescope combination

An excellent telescope and equatorial mount combination. The Advanced VX mount box weighed 61 pounds and measured 37 inches long by 26 inches wide by 12 inches tall. The EdgeHD 8 inch telescope box weighed 22 pounds and measured 25 inches long by 15 inches wide by 14.75 inches tall. The mount and tr...

Scope is incredible. Wish the mount was more powerful.

Best optics for the size of mirror and cost.

Very good Telescope, the optics are about as you're going to get in this size, and the light transmission through the front glass is maximized through the coatings on it. The mount tracks very well, and without an autoguider I'm able to get 120 second exposures without star trails. The mirror focus ...
