The Celestron NexStar Evolution 8" Edge HD is a Schmidt-Cassegrain telescope with a 203.2 mm aperture. Its Edge HD optics produce images free of coma and field curvature. It is made for both visual observing and astroimaging of galaxies, nebulae and star clusters.
StarSense AutoAlign aligns the telescope in a few seconds. Built-in WiFi works with the Celestron SkyPortal app for iOS and Android, so you can control the telescope from a smartphone or tablet. It is compatible with the Fastar/HyperStar system for imaging at f/2, with no wedge or autoguider needed.
The single-arm mount has precision-machined worm gears on both axes. The accessory tray is illuminated, and a USB charging port lets you charge electronic devices from the telescope. A rechargeable lithium-ion battery gives up to 10 hours of use.
