Product Info for Celestron NexStar Evolution 9.25 Schmidt-Cassegrain Telescope

The Celestron NexStar Evolution 9.25in Schmidt-Cassegrain Telescope w/ WiFi 12092 has been designed to be the ideal telescope for the avid astronomer. The first Schmidt-Cassegrain telescope to feature WiFi, this Astronomy Telescope from Celestron lets you leave your hand control behind and slew to all the best celestial objects with a tap of your smartphone or tablet. 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. The proprietary SkyAlign alignment procedure is built right into the Celestron mobile app, so you're ready to observe within minutes. For the first time ever on a consumer telescope, the Celestron NexStar Evolution 9.25 Astronomy Telescope 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. If you're interested in astroimaging, the Celestron 9.25-inch NexStar Evolution is an excellent, affordable way to get started. It is the only fork-mounted telescope in its price range that offers brass worm gears, along with improved motors. The tracking accuracy of the Celestron NexStar 9.25in Evolution Telescope 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 Pro HD Wedge to achieve longer exposures for more detailed astrophotos. 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. The NexStar Evolution 9.25 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 Celestron Evolution 9.25 NexStar Telescope also includes a StarPointer finderscope, two 1.25" Plossl eyepieces, a 1.25" star diagonal, and an AC adapter.image
