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 lithium-ion 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. Setting up your 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 astroimaging If you’re interested in astroimaging, the 9.25-inch NexStar Evolution is an excellent, affordable way to get started. It’s the only fork-mounted telescope in its price range that offers 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 Celestron's 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. NexStar Evolution includes a StarPointer finderscope, two 1.25” Plossl eyepieces, a 1.25” star diagonal, AC adapter, and optional hand control.
