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.
Accessories Included
The NexStar Evolution 8” telescope includes two 1.25” Plössl 40mm & 13mm eyepiece, which is great for observing most any celestial object right out of the box. What’s more, your telescope includes a 1.25" star diagonal, 1.25” Visual Back, the StarSense AutoAlign accessory, and a StarPointer Pro™ finderscope. The StarSense AutoAlign comes with a hand control, but thanks to the internal WiFi and SkyPortal app, use of the hand control is completely optional.
To increase your field of view without sacrificing performance, add the optional EdgeHD reducer lens, bringing your focal ratio down to f/7.
Software that Comes FREE with your Purchase
Celestron PWI Telescope Control: Your Ultimate Astronomy Software
All current Celestron computerized telescopes include Celestron PWI (CPWI), the most advanced astronomy software provided with any consumer-grade telescope. Celestron’s experts co-developed CPWI with the engineers at PlaneWave Instruments. The result is an all-in-one solution offering you many of the same features used on PlaneWave’s observatory-class telescopes.
- Graphical planetarium interface with PointXP advanced mount modelling allows you to add 100+ points to your alignment model for the most accurate pointing and tracking possible
- Ideal for remote observatory setups: save and re-load your alignment and park your scope
- Provides a complete ASCOM telescope interface to allow control of the telescope from third party software applications

What is the heaviest recommend load for mounting a camera in the Fastar / HyperStar configuraton?
We recommend a load of no more than 20 lbs. at 4.5 inches away from the 8" Schmidt corrector.
Q:
Why doesn’t my red dot finderscope match the image on the box/website?
Why doesn’t my red dot finderscope match the image on the box/website?
Celestron is making a change to the finderscope shipped with some Celestron telescopes. In some cases, you may receive a finderscope that is different in appearance than the one pictured on the gift box, manual, Quick Setup Guide, or website. We apologize for any inconvenience this may cause. Rest assured that the finders are identical in performance and features. The main difference is the location of the battery compartment and, therefore, the battery installation instructions.
If your red dot finderscope looks like the unit pictured here, you can ignore this message.

If you received a red dot finderscope that looks like the unit pictured here, follow the instructions below to replace the battery:

1. The battery compartment on this finderscope is located on top of the unit. Use a Philips-head screwdriver to loosen the screw holding the battery door closed. The screw is captured and will not fall out when you open the battery door.

2. Lift the battery door open to expose the CR-2032 button battery.
3. With your fingernail on either side of the battery, pry the battery up and out of the battery compartment.
4. Place the new CR-2032 battery, positive (+) side up, under the two copper battery clips at the front of the battery compartment.


5. Press the battery down to snap it into the plastic battery clips on the opposite side of the battery.
6. Close the battery door and tighten the Phillips-head screw to secure the door in place.
Q:
I’ve heard there is a firmware update for NexStar Evolution. What’s it for, and should I install it?
I’ve heard there is a firmware update for NexStar Evolution. What’s it for, and should I install it?
Yes! This important update improves your NexStar Evolution mount’s tracking performance and electrical stability, along with helping to prevent potential motor control board issues seen in a small number of units. It also adds a new feature that shuts down auxiliary devices when the mount’s internal battery gets critically low. To make the update process quick and easy, our engineers created a special version of the Celestron Firmware Manager (CFM) just for Evolution owners. We recommend all NexStar Evolution owners install it by visiting celestron.com/evocfm
