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.

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 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
The 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

The Star Sense really works. It hunts around the sky, takes pictures, recognizes star patters and then tells you it is aligned. The first time you use it, you need to use manual align so that the Star Sense camera aligns itself to the telescope. This is a one time thing and sounds more complicated than it is. The alignment worked well.
Once aligned with star sense (using Auto Align), I selected M57 the Ring nebula and the Evolution scope put it right in the center of the eyepiece...amazing. I picked one celestial object after another (Saturn, Andromeda Galaxy, Dumbbell Nebula, Double Double cluster, Epsilon Lyra, etc.) and each time the Evolution scope landed the item in the center of the eyepiece. It never missed. This happened on repeated nights. When you auto align it asks you to first put the optical tube in the horizontal position. You don't have to be exact in this. A close approximation seems to be all that is required. Nice!
I'm so satisfied with the Evolution HD scope that I will likely sell my 102mm Stellarvue. The 8 inch diameter definitely gives you a more satisfying view of deep sky objects than the 4 inch diameter of the refactor (at least for me).
I updated the firmware in the telescope...be mindful that it updates the motor software, the Star sense and the hand controller firmware. The documents that come with the scope make you think you need a serial cable with a serial to USB converter cable. You don't. The engineers updated the cable ports so what you need is a USB to mini USB cable. What I couldn't figure out is whether you need one cable or two cables to accomplish all the firmware updates. I've read mixed messages on the Internet. I used only the one cable.
Lots of things have been well thought out in the Evolution HD...like captive screws in the tripod, centering help to place the telescope in the mount, the built in lithium battery (no more batteries to trip over in the dark), handles on the base and next to the battery to help carry the telescope, a leveling bubble on the base. To properly balance the optical tube note from the picture that most of it sits forward so you can read the entire Evolution logo.
The HD optical tube seems to be of very high quality. The optics are great. Even though my scope was shipped from NY to Hawaii, the scope arrived in perfect collimation.
Note that if you decide to attach a reducer to the EvolutionHD in order to get a wider field you can't use the old Celestron reducer. You'll need to get the newer .7 celestron reducer which is more expensive. It is also difficult for dealers to get. Not sure why Celestron is not delivering more to the dealers.
All in all this scope is HIGHLY RECOMMENDED.

From the seller I recieved accurate feedback and helpfull assistace to get the delivery completed, for it was a very large box!
The scope OTA is fantastic and I have always wanted to upgrade (from a 127 MAK) but do not have the time or skill to set up an EQ mount. When the Evolution series came out I was very interested so i finally took the plunge.
The wifi ability to run the scope through a tablet is a big draw. But you can also use the handset which comes with it and this is a great back up (make sure you disconnect the handset when using wifi. I had read a bit online so I was aware of a few quirks.
Out of the box if you set the scope up as per the instructions.. align the finder etc charge up the battery then you are ready to go. In its two parts it is not too heavy but it is solid as a rock when put together. Useful bumps and notches help you do it easily in the dark (snigger). I was set up in less than 5 minutes on the first clear night. I was a bit dubious of the tablet alignment.. but sure enough.. line up 3 bright stars and the scope knows exactly what you are doing.. all GPS data and time information comes from the tablet... IT IS SO EASY and it works.... the Skyportal software is easy to use but I advise playing with it inside first as it is a bit quirky. The tracking works great as well.
The heavy tripod and mount hold the 9.25 very steady even with a DSLR mounted to it.
I have been using a nexus 7 to control it. I found it best to disconnect my local wifi.. run a GPS test app and check location before starting the skyportal program.
The eyepieces that come with the scope are ok but it is better to upgrade them.
Having a visual planetarium in front of you means you see a lot more in one session that you might not have known was even there before... Even as a relative novice it has opened my eyes to what is in the sky. Just have to wait for some clear nights.
I then went on the Internet to the American forums on astronomy and found other people have had the same problem and is easy to sort out, all you need to do is just use one of your devices to connect telescope to also to make sure you tell it to forget your own Wi-Fi Internet server then connect to Skye link and then Sky portal, is now works first time every time. What was happening was it was trying to connect to 2 devices at the same time and was getting confused so make sure any other devices you've tried it on are turned off.
My first trip out I connected it to Wi-Fi sky link and then used 13mm eye piece to do the three star alignment, all done within 5 min, I used Jupiter Betelgeuse and Rigel.
After it completed three star alignment I clicked on go to Jupiter it went straight to it right in the centre of eyepiece I then left it for 45 mins on Jupiter when I came back it was still in the centre tracking well, I have used it four times now and each time is connected first time and done everything it is supposed to do with no problems. It is a fantastic scope before I had a sky watcher 127 goto but this scope is something else.
I now use my Nexus 7in it’s about the right size to control scope.
Just a couple of hints
Put telescope outside for at least an hour and a half to cool down , I use a telescope all weather cover on it from green witch cost £29.95 and Celestron dew shield from 365 astronomy also £29.95.
Make sure you disconnect from your own Wi-Fi server before you connect to Sky link and make sure any of the devices you have Sky Portal on are turned off.
I hope this helps other people who might have problems connecting.
I'm pretty sure the product is fantastic and i still want it but without the mount its not particularly useful, so please only take this as a comment on Amazon.
I've had many different scopes and mounts and this is by far the best - really can't fault it. By the way you might feel a little play in the alt bearing - this is not a problem, just make sure your scope is slightly back heavy (by moving it in the dovetail until it tilts back slightly) and goto is absolutely spot on. Oh and buy a illuminated reticule eyepiece for your goto set up.
