Product Description

"This robotic WiFi telescope is the coolest app-cessory in the galaxy" – Wired Meet NexStar Evolution 8, the first WiFi-enabled Schmidt-Cassegrain telescope. Slew to all the best celestial objects with a tap of your smartphone or tablet. Celestron’s SkyPortal app for iPhone and Android makes it easy. Celestron engineers designed NexStar Evolution to be the most user-friendly computerized telescope ever. Our proprietary SkyAlign alignment procedure is built right into the app, so you’re ready to observe in minutes. From there, use the planetarium interface or the list of Tonight’s Best objects to select a target to view. Forget about batteries or an external power supply; NexStar Evolution includes a lithium-iron phosphate battery that lasts 10 hours. You can even use the telescope’s USB port to charge your phone while you observe. Setting up NexStar Evolution is quick and painless with large, ergonomic handles. Manual clutches in both altitude and azimuth allow you to manually point the telescope when powered off. If you’re interested in astroimaging, the 8-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 and improved motors. NexStar Evolution’s tracking accuracy is so impressive that you can capture images of deep-sky objects like the Orion Nebula by simply attaching your DSLR camera. 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. 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 red dot finderscope, 2 1.25” Plossl eyepieces, a star diagonal, and an AC adapter.

Customers are mixed about the ease of use of the telescope. Some mention that it's easy to assemble, not too hard to learn how to use, and the app is very easy to use.

10 customers mention5 positive5 negative

Customers have mixed opinions about the value of the telescope. Some find the compact design a little pricy for an armature, while others say that the price is high. Some customers also mention that the finderscope is cheap, good for a lower tiered scope, and the price of the scope is high, making it an expensive manually slewable scope. Overall, the opinions are mixed and the telescope is not up to the improved telescope.

"...these are a great set of eyepieces at a great price and gives you a good selection with colored filters add in the 2 celestron eye pieces that come..." Read more

"...In a word, the finderscope is cheap...good for a lower tiered scope. Celestron should be providing something better...." Read more

"This is a great scope decent price. It came with prime in two days which was fantastic...." Read more

"...This is a less than ideal solution because it sets the optical tube assembly (OTA) about an inch further back than is the case with the 8-inch..." Read more

Fantastic scope. Very happy with the results. see picture of Jupiter
5 Stars
Fantastic scope. Very happy with the results. see picture of Jupiter
This is a review for the 9.25"Quite impressed with this telescope. I upgraded from a 8" and there is a significant difference.The telescope arrive in several pieces (tripod, mount, OTA), putting it together is very easy and takes just a few minutes.The tripod is very sturdy and stable. Also it can be closed without removing the spreader. It has a strap on one of the leg that can be used to keep the tripod closed during transportation. The spreader is metal, not plastic, so solid and convenient to store eyepieces.The mount is solid and rather heavy and is secured to the tripod with spring loaded knob. An improvement versus the 8".Once everything is assembled, I can still move it around in a single piece, even if just for a few meters (ie from inside the house to the backyard were I do the observation) w/o having to take everything apart. If I drive somewhere, I need to separate and collapse the tripod from the rest.WiFi connection to mobile device simplify the alignment. The scope takes position and time from the mobile device GPS, so you are left with only pointing to three stars. Much faster vs my previous Nerxstar 8SE, where you need to punch in location, city, time zone etc.However the mobile app is not as stable as I would have liked. Sometimes crashes, sometime lose connection to the scope... very often is not responsive or you just make a tap on a movement arrow...and the scope keeps moving, because the app is stuck and thinks you are still pressing the moving button. The delayed response often causes you to overcorrect when fine aligning objects. Infact now I use the app for alignment setup, for GoTo, but all the scope movement, fine tuning, corrections are done via the handheld device... to avoid the overcorrections, and the annoying unresponsiveness of the app. The app need some definitive improvement.The finderscope is the same of the 8SE, and not up to the improved telescope. Does the job, but the red light is a bit too big, the collimation of the finderscope is difficult and not very stable. In a word, the finderscope is cheap...good for a lower tiered scope. Celestron should be providing something better.Also the Evo 9.25 doesn't come with the RS232 cable for firmware upgrade. Seriously? a 2K$ scope without a necessary 5$ cable. Not sure which misguided marketing decision is that. The cable was included in my previous 8SE which cost half the money. initially I assumed it was because you can upgrade firmware via the WiFi, but it isn't the case.Another thing I noticed for this scope vs the 8SE, is that I need to collimate the optic very often, almost every use. It arrived way off collimation, and maybe because of the larger optics, doesn't seem to keep collimation after having moved.Chromatic aberration is also more significant than the 8SE.Motor is significant better than the 8SE, much more precise, accurate and effective, keeps alignment much better... it is also quite more noisyAnother useful improvement, is the red light projected on the mount were there is space for some eyepiece, which is very helpfulNOTE: buy as well the Vibration Suppression Pads ASIN B0000665V7... they make a VERY significant difference, truly reducing wind induced vibration, or vibration created by you focusing on object VERY significantly. Vibrations stop immediately as soon as you aren't touching anything, vs w/o pads were it takes a couple of seconds moreThe scope was bought via Adorama (ASIN B0172UR7QU) which is the same and comes bundled with an eyepieces kit for free . Fantastic customer service, very happy with packaging, shipment and the interactions I had with their customer support.In conclusion, it has an aperture large enough to do some very decent observation and photography even in a city polluted light, and still compact enough that it can be easily transported and moved around. It has significant improvement and features vs the Nexstar 8SE: much sturdier tripod, better motor, wifi that enable you to use GPS of a mobile device, overall more solid and professional.Anyhow, see the attached pictures taken with the Evo 9.25 and a Neximage 5, processed with PIPP and Registax 6

This is a review for the 9.25"
Quite impressed with this telescope. I upgraded from a 8" and there is a significant difference.

The telescope arrive in several pieces (tripod, mount, OTA), putting it together is very easy and takes just a few minutes.
The tripod is very sturdy and stable. Also it can be closed without removing the spreader. It has a strap on one of the leg that can be used to keep the tripod closed during transportation. The spreader is metal, not plastic, so solid and convenient to store eyepieces.
The mount is solid and rather heavy and is secured to the tripod with spring loaded knob. An improvement versus the 8".

WiFi connection to mobile device simplify the alignment. The scope takes position and time from the mobile device GPS, so you are left with only pointing to three stars. Much faster vs my previous Nerxstar 8SE, where you need to punch in location, city, time zone etc.
However the mobile app is not as stable as I would have liked.

Chromatic aberration is also more significant than the 8SE.

Motor is significant better than the 8SE, much more precise, accurate and effective, keeps alignment much better... it is also quite more noisy

Another useful improvement, is the red light projected on the mount were there is space for some eyepiece, which is very helpful

NOTE: buy as well the Vibration Suppression Pads ASIN B0000665V7... they make a VERY significant difference, truly reducing wind induced vibration, or vibration created by you focusing on object VERY significantly. Vibrations stop immediately as soon as you aren't touching anything, vs w/o pads were it takes a couple of seconds more
