Premium EdgeHD optics with 9.25-inch aperture provide distortion-free images, paired with a heavy-duty CGEM II mount for smooth tracking and advanced astrophotography.

The innovative NexStar Evolution is a compact, portable, and mechanically solid telescope made for hours of serious visual observing and certain types of astroimaging. The NexStar Evolution HD package stands out due to its unique features, including: StarSense AutoAlign, EdgeHD optics, integrated WiFi, and its internal LiFePO4 battery. StarSense AutoAlign in the SkyPortal App-StarSense AutoAlign helps you optimize your time outdoors, giving you back time you would have spent aligning your telescope and allowing you more time to observe. It scans the night sky and analyzes the star patterns overhead, automatically calculating the telescope’s precise location, the date, and the current time. What’s more, you can add up to 10 additional alignment stars for the most accurate alignment possible. Learn more about the StarSense technology. Because StarSense AutoAlign is paired with the Evolution mount, you get even more functionality and ease of use. Connect to the mount via the SkyPortal Powered by SkySafari™ mobile app and you can perform the automatic alignment directly from your smart device, then instantly command the telescope to slew to your first celestial object. 8” EdgeHD Optical Tube - EdgeHD is an aplanatic, flat-field Schmidt optical system that produces aberration-free images across a wide visual and photographic field of view. The optical system reduces more than just off-axis star coma; it provides an astrograph-quality flat focal plane all the way to the edge of the field of view. EdgeHD optics produce a focal plane more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across full frame sensors. The 8” EdgeHD flat-field and coma-free optical tube was made to accommodate modern imaging with cameras of all types, especially larger format CCD and DSLR cameras. The EdgeHD optical tube is Fastar-compatible for ultra-fast f/2 wide field imaging with an optional, third-party lens assembly. Perfect for Visual Use or Beginning Astroimaging-This telescope is an excellent instrument for those looking to explore astroimaging. It’s the only fork-mounted telescope in its price range that offers brass worm gears along with improved motors, which provide great tracking accuracy. Capture images of the Moon and planets by attaching any planetary imaging camera. You can even experiment with imaging brighter deep-sky objects like the Orion Nebula with your DSLR camera. As you progress in the hobby of astroimaging, turn your alt-azimuth mount into equatorial setup by adding the Wedge for NexStar Evolution. This accessory will enable you to achieve longer exposures for more detailed astrophotos. The NexStar Evolution mount also features a built-in lithium-iron phosphate (LiFePO4) battery with enough power for 10-hour astroimaging sessions. Of course, the EdgeHD optical system offers bright, sharp views with StarBright XLT™ optical coatings—a great choice for visual observers and budding astro-imagers alike. NexStar Evolution is equipped with 4 auxiliary ports—two on top of the fork and two on the bottom. A StarSense hand control is still included, but is not necessary when using NexStar Evolution with the app.

Optical tube in one hand and tripod in the other? Still carrying your bulky telescope box to remote observing sites? Let us lighten your load with our sleek, padded, protective telescope soft case. This all-in-one storage solution is the perfect choice for transporting your telescope setup anywhere with ease and confidence. It's truly a must-have for telescope owners of all stripes. Ultra-durable Material The Telescope Soft Case is constructed from 900 denier polyester for durability and weather resistance. Its walls are lined with 16mm thick EPE foam to protect your gear. The bottom panel is reinforced with a hard layer of PVC for extra protection from minor bumps. On the exterior, you'll find hard rubber elements that provide extra strength and water resistance. Design your Custom Case Unzip the case and you'll discover a soft polyester interior lining with three configurable EVA foam padded walls. Use the Velcro to place the foam walls in the exact configuration you need for your equipment, creating custom compartments for your optical tube, mount, and tripod. Once your equipment is stowed safely inside, secure it in place with the internal straps. With shorter tubes, you'll have some leftover interior space to stash extra accessories. In addition to the configurable compartments inside, the case features a bonus 9" x 12" padded accessory bag and an external zippered pocket, for holding eyepieces and other accessories. Lastly, you'll find sewn-on fabric loops on the outside of the case. Use these to clip even more accessories to the exterior of the case. Grab and Go Transport your case one of two ways: via the pair of sewn in handles or optional, clip in padded shoulder strap for hands-free carrying.

The NexStar Evolution is the first Schmidt-Cassegrain 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 SkyPortal Powered by SkySafari™ 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 SkyPortal 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-iron 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 same heavy-duty stainless steel tripod we use on our CPC series telescopes anchors your 9.25" telescope, providing serious stability. 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 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 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 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.
