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.

Tüm astronomik uygulamalar için kesinlikle ideal bir ürün. Astronomide maalesef üst sınır diye birşey yok. Ne kadar masraf edilse de hep daha üst birşeyler karşınıza çıkar ve acaba daha üstünü mü almalıyım diye düşünürsünüz. Ne alırsanız alın James Webb karşısında daima çaresiz kalacaksınız. Dolayısıyla alışlarınıza maddi bir sınır koymanız gerekir. Bu model yıllarca bir çok gözlem ihtiyacınıza hizmet edecektir. Tabiki devamında çeşitli göz mercekleri, filtreler, fotoğraflama aksesuarları vs.almanız gerekecek. Bir yerden başlamanız gerektiğine göre bu modeli şiddetle tavsiye ederim.

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.

Amazon have not learned and are still trying to sell the OTA only via Warehouse. DO NOT BUY!!! It looks like they've done that 3 times at least now in the past 9 months or so... ridiculous... now have to return a rather large box.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 had a few problems getting this through Amazon but some amazing customer service fixed the problems in the end.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.

The 8" SCT is great - better than a Meade 8" I had several years ago. However the star of the show is the mount - very stable, very accurate goto and really easy to set up - just point at 3 bright objects, centre in the eyepiece (using controls on your Ipad) and everything is synced. A word of advice - buy the Skysafari Pro app rather than use the free Celestron - it is so much better and and there are many more objects to view.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.

Okay. I'ts been about three months now and I am comfortable enough to write a fair review. First, the design is gorgeous and very portable. I purchased a very large Pelican case to transport it in and I take it around often to different sites. Dis-assembly and reassembly are a breeze and I am never afraid that I'm going to snap a bolt or break a leg. You can by vibration suppression pads but I so far haven't had the reason to do so. I can observe planets and nebula without deviation, the image is not shaky. I also take images with this scope and I so far have not had any blurry images. The alignment software worked the first time and every time. I did what Celestron instructed, pick three bright objects near three different cardinal directions and that was it. The manual control from the App works great too, I can use them without looking at my tablet and get exactly where I need to go. The App is wonderful by the way, but I'll review that on another day. My telescope arrived in perfect condition, no smudges, no compromise of the seal, no scratches no missing parts. No complaints. The finderscope isn't the best but it works every time for me, just line it up right. I can place it on a star perfectly and there it is, centered in the eyepiece.The images are beautiful. Not much else to say. I've seen nebula and planets and stars in my other telescopes but this scope is something else.I haven't dealt with Celestron customer service, can't attest to that. So far no problems, so I can't talk about the warranty. Will update if anything changes.UPDATE 6 years later!Boy, this telescope has been through the wringer. I've been caught in the rain, had fierce winds, had it jumble around in the back of a jeep and truck, had it out in crazy humidity and heat as well as bitter cold. The tripod has taken a beating after being assembled and disassembled so many times.At one point, the charging port of the motor caved in on itself and disappeared somewhere into the telescope. I was able to gently take it apart, find the female end, and continue charging/using the telescope without a hitch!It still has clear, crisp, incredible images. I have never had the suspicion of a breach; there has never been any moisture inside the aperture or any other reason to believe that the vacuum seal has failed. The mirror is still in great shape and I am thrilled with this investment. It impresses night after night.Highly recommend.
