Celestron NexStar Evolution 8 WIFI SCT Telescope - 12091

Celestron's signature telescopes reach a new level with the Celestron NexStar Evolution, the first Schmidt-Cassegrain Celestron Telescope with integrated WiFi. Leave your hand control behind and slew to all the best celestial objects with a tap of your smartphone or tablet. 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. Celestron's proprietary SkyAlign alignment procedure is built right into the Celestron NexStar Evolution mobile app, so you're ready to observe within minutes.

The most user-friendly Celestron telescope ever...

Celestron engineers designed the Celestron 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, the Celestron NexStar Evolution includes its own built-in lithium-ion battery. You'll be able to enjoy stargazing marathons with 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.

Setting up your Celestron NexStar Evolution is quick and painless with large, ergonomic handles. The steel tripod features leg etchings to 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 astro-imaging... 

If you're interested in astro-imaging, the Celestron NexStar Evolution 8 is an excellent, affordable way to get started. It's the only fork-mounted telescope in its price range that offers worm gears as well as improved motors.  The 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 the Celestron HD Pro Wedge to achieve longer exposures for more detailed astrophotos.

Of course, the Celestron Schmidt-Cassegrain optical system offers bright, sharp views with StarBright XLT optical coatings - a great choice for visual observers and budding astro-imagers alike.

The Celestron 8" NexStar Evolution includes a StarPointer finderscope, two 1.25" Plossl eyepieces, a 1.25" star diagonal, AC adapter, and optional hand control.
