The Celestron NexStar Evolution 8 HD is a computerized Schmidt-Cassegrain telescope with 8-inch EdgeHD optics on the single fork arm NexStar Evolution mount. The optics are free of coma and field curvature. They are made for visual observing and for astro-imaging with cameras of all types, including larger format CCD and DSLR cameras.
StarSense AutoAlign aligns the telescope automatically when you tap "Connect and Align." After alignment, the fully motorized go-to mount takes you to objects with a tap on your smartphone. Built-in WiFi connects the telescope to a computer, smartphone or tablet, so no hand controller is required. It works with the SkyPortal app, and with Starry Night or SkySafari for iOS, macOS and Android.
The mount has manual release clutches and precision machined worm gears on both axes. The accessory tray has lighting and a USB charge port. A rechargeable lithium-iron battery provides power for 10 hours of continuous observing. The telescope is Fastar/HyperStar compatible for imaging deep sky objects at f/2, which can often eliminate the need to autoguide or track on a wedge.
