The Celestron NexStar Evolution 8 EdgeHD is a computerized go-to Schmidt-Cassegrain telescope on a single fork arm mount. It combines 8-inch EdgeHD optics with StarSense AutoAlign and wireless control from a smartphone or tablet. The EdgeHD optical system is flat-field and coma-free, and StarBright XLT coatings are used on the optics.
StarSense AutoAlign aligns the telescope automatically from the SkyPortal app. The app also lets you enter up to 10 additional alignment points for mount modeling and more precise pointing. After alignment, you can select an object and have the telescope slew to it with a tap. The mount has brass worm gears and improved motors for tracking.
The telescope suits visual observing and astroimaging. A DSLR camera can attach directly, and the Celestron Wedge for NexStar Evolution can be added for longer exposures. The mount has four auxiliary ports: two on top of the fork and two on the bottom. The StarSense hand control is included but is not needed when using the app.
