The NexStar Evolution keeps evolving. Celestron paired its best optics with the best technology to make an incredible versatile and portable telescope system. Now, enjoy EdgeHD 8” optics and StarSense AutoAlign on the renowned Evolution mount, all controlled from your favorite tablet or phone.
When NexStar Evolution was introduced, it paired two of Celestron’s most acclaimed innovations, Schmidt-Cassegrain telescopes and computerized go-to optics, in a compact single fork arm mount. The technology and optics continued to evolve over the years. On the technology side, Celestron added StarSense AutoAlign for the go-to telescopes, as well as WiFi telescope control with over the new SkyPortal app. With optics, EdgeHD flat-field and coma-free astro-imaging systems were made to accommodate modern imaging with cameras of all types, especially larger format CCD and DSLR cameras. Now all of these innovations have come together in one telescope package: The NexStar Evolution 8 inch EdgeHD. The NexStar Evolution 8 inch EdgeHD covers all bases for compact and easy to use, and is perfectly capable for any observing to astro-imaging pursuit.
Superior Fit
If you’re interested in astroimaging, the 8 inch NexStar Evolution EdgeHD is an excellent way to jump in. It’s the only fork-mounted telescope in its price range that offers brass worm gears, along with improved motors. Tracking is great, and so too is the flat-field, coma-free EdgeHD optical system.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 Celestrons Wedge for NexStar Evolution to achieve longer exposures for more detailed astrophotos.
Of course, the EdgeHD 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 StarSense hand control is still included, but is not necessary when using NexStar Evolution with the app.
Technologies
Celestron added the StarSense AutoAlign technology to the SkyPortal app, making SkyPortal the most advanced telescope control app offered. StarSense not only automatically aligns itself from your smartdevice, it also has advanced mount modeling, allowing you enter up to 10 alignment points for the most precision pointing accuracy possible. Even the most advanced telescope users will love using StarSense AutoAlign through the app. This affordable accessory replaces the expensive software usually used for advanced mount modeling.
With built-in mount modeling, you'll get superior pointing accuracy from horizon to horizon. When your alignment needs to be perfect, add up to 10 additional calibration stars to achieve a new level of accuracy, great for locating objects in the camera’s field of view for astroimaging.
SkyPortal App
Access the sky and control your telescope from an interactive planetarium on your smart device with a free SkyPortal app – provides the best star gazing experience for you and your friends and family – know when Jupiter’s Great Red Spot will be visible, including shadow transits, planetary occultations, conjunctions, or pick the best deep sky objects to view such as galaxies and nebulae.
