Connect your device to NexStar Evolution s built-in wireless network, and explore the universe with the Celestron mobile app for iOS and Android. 
Use the planetarium interface to view the night sky in real time or display a list of celestial objects currently visible based on your time and location. Our proprietary SkyAlign alignment procedure is built right into the Celestron mobile app, so you re ready to observe within minutes.
The most user-friendly telescope ever
 Celestron engineers designed NexStar Evolution based on years of customer feedback. It offers many thoughtful design features that combine to provide you the best possible experience out under the stars.
Forget about batteries or an external power supply. For the first time ever on a consumer telescope, NexStar Evolution includes its own built-in battery. With this ultra-long life lithium-ion phosphate battery, you ll be able to enjoy stargazing marathons up to 10 hours on a single charge. You can even use NexStar Evolution s USB charge port to top off the other devices in your life that need to stay powered on during an observing session. An intelligent power management system senses when battery levels are low and goes into power-saving mode to keep your telescope running for as long as possible.
Setting up your NexStar Evolution is quick and painless with large, ergonomic handles. The all-metal tripod features a metal accessory tray with indentations for storing and carrying the tripod. During setup, leg etchings help you achieve a level, uniform height for your telescope. Manual clutches in both altitude and azimuth offer greater flexibility to manually point the telescope when powered off. Store up to 7 eyepieces in 2 accessory trays, one with an adjustable red LED illuminator.
Superior tracking fit for astroimaging
 If you re interested in astroimaging, the 8-inch NexStar Evolution is an excellent, affordable way to get started. It s the only fork-mounted telescope in its price range that offers brass worm gears, along with improved motors. NexStar Evolution s tracking accuracy is so impressive, you can capture images of deep-sky objects like the Orion Nebula by simply attaching your DSLR camera.  As you progress in the hobby of astroimaging, you can add our HD Pro Wedge to achieve longer exposures for more detailed astrophotos. NexStar Evolution compatible with the wedge when used with the CPC tripod (sold separately).
Of course, the Schmidt-Cassegrain optical system offers bright, sharp views with StarBright XLT optical coatings a great choice for visual observers and budding astroimagers alike.
NexStar Evolution is equipped with 4 auxiliary ports--2 on top of the fork and 2 on the bottom. A classic NexStar+ hand control is included, but is not necessary when using NexStar Evolution with the mobile app. The telescope also includes a StarPointer finderscope, two 1.25  Plossl eyepieces, a 1.25  star diagonal, and an AC adapter.
