I have owned about 20 to 30 telescopes over the past 40 years, including 4 previous Celestron 8 scopes. I've owned large Dobs (Teleports and Starmasters), Refractors (Tele Vue and Stellarvue) and even a Meade or two. I was intrigued by the Celestron Evolution EdgeHD with Star Sense. I was not disappointed. The GoTo feature is fantastic. 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.

Great scope. Enjoy it very much. The starsence works pretty well using the hand controller. I've had very little success using wifi and my iphone to control the telescope. The wifi is unreliable and difficult to control the unit. It disconnects constantly and sometimes sends the telescope out of control. Using WiFi, at one point, the telescope moved vertically until it was upside down and the 40 mm eyepiece struck the base and popped off before I could get to the power button to turn it off. No such problem using the hand controller. Also, I had to purchase the GPS unit because using just the hand controller you have to input the time, date, and location manually. Adding the GPS unit allows that to happen automatically making it much easier. That being said, it's a great scope and I have used it many times since my wife bought it for my birthday. Lastly, the battery is great. I've run the unit for hours and the battery has never died. I think you could go all night with it.

Only had the scope for 2 days and already experienced many issues. There are significant imperfections on the objective lens.. I thought it was dust at first but it is not. Looks like it is in the glass. It loses direct and access network connection even within 2-3 feet when you try to give the scope commands. The slew motors stoped working the second time I tried using it. I’ve tried the hand controller and the app and it is not working. I am so disappointed. I have over $4K wrapped up in the scope and accessories and it is all unusable.

I started with StarSense autoalign. The scope says "successfully aligned", and then points Sirius at the other end of the sky. I then aligned it manually and used goto to point M42. The scope started endless spinning around itself, breaking the power socket (which is telling of the quality). Of course, they use non-standrd screws so impossible to open it to replace the socket inside. Wifi is a joke, it will only connect 1 time out of 5. The manual says "if there are too many wifi networks, the scope might not be able to use wifi". Come on, all my other wifi devices are working properly - use a proper wifi module. The goto list of Galaxies is not ordered alphabetically, and is very long, which makes it impossible to find the one you're looking for. On top of this, their Android apps keeps on freezing. Very low quality. Software Don't buy that telescope!
