Description

Celestron has reinvented the manual telescope with StarSense Explorer—the first telescope that uses your smartphone to analyze the night sky and calculate its position in real time. StarSense Explorer is ideal for beginners thanks to the app’s user-friendly interface and detailed tutorials. It’s like having your own personal tour guide of the night sky. Dock, Launch, Explore Leave complicated star charts, imprecise planetarium apps, and computerized mounts behind. With StarSense Explorer, locating objects has never been easier, faster, or more accurate. Within minutes of setting up the telescope, you’ll be navigating the sky with confidence. Simply place your phone in the unique StarSense dock and launch the StarSense Explorer app. After aligning your phone to the telescope’s optics (a quick, 2-minute procedure), StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear onscreen, guiding you as you to move the telescope. When the object is ready to view, the bullseye turns green. Smartphone Compatibility StarSense Explorer works with most modern smartphones, including iPhone 6 and up and most devices running Android 7.1.2 or later manufactured since 2016. Patented StarSense Sky Recognition Technology StarSense Explorer uses patented technology and your smartphone to determine exactly where the telescope is pointed in the night sky. A Lost in Space Algorithm (LISA), like the ones satellites use in orbit to correctly orient themselves, helps the app match star patterns it detects overhead to its internal database. While other astronomy apps may claim that they can help you find objects, they rely exclusively on the phone’s gyros and accelerometers, which aren’t as accurate as LISA technology. No other app can accurately tell you when your target is visible in the eyepiece.

    • Great for a beginner like myself
Style: StarSense Explorer DX 102
It is very easy to set this telescope up. It is also very lightweight and can be carried around. I like that it comes with two eyepieces. It was the First night in my entire life that I started to look at sky with a telescope. I stared at Saturn for a sweet one hour. Could not stop looking at that beautiful ring of hers. I cannot believe how easy it was to located and lock my view at it. The red-dot is awesome, if the object is visible with naked eye. I also was able to find Andromeda. It was harder and took me a while, since red dot was not much useful and I had to use the app. App is awesome. However it helps to get to the proximity of the celestial object. It is a bit hard to calibrate the cellphone, and I had to do the calibration, frequently. All in all, it was a memorable night for me. I highly recommend this telescope. ... show more

    • Good Scope, OK Mount, GREAT App.
Style: StarSense Explorer DX 102
You are definitely paying for the R&D for the app in the cost of this scope. That being said I think it is great for people just getting in to or returning to the hobby. I picked up this scope to get back into the swing of things after about 20 years away from the hobby. The app does an amazing job of finding things the first time, every time. I've been using the scope for a few weeks now and the app hasn't failed me once. The scope is good, not great. At 102mm it gives you enough light for visual astronomy of the planets, clusters and brighter DSO's. One of the big pluses is that the refractor design is maintenance free, no collimation required here. The focuser on mine is a bit gritty and can be hard to get focused when you're really trying to dial in the sharpness. The eyepieces are typical of what you will see in low cost scopes, I upgraded to Celestron X-Cel eyepieces and it was an AMAZING difference. Now for the mount, oh lord the mount.... The base of the tripod is, again, typical of a low cost scope, provides enough stability to get the job done. The single fork design is both the best and worst part of the mount. It is made out of amazingly cheap plastic, the movement and slow motion controls are friction based and tend to be either too tight or too loose, finding the sweet spot has thus far eluded me. The scope shakes badly after focusing or movement and you will have to wait a few seconds for things to calm down. But also on this fork mount is the phone holder/mirror that makes the StarSense app work, and boy oh boy does it work. Celestron also makes these in reflector and dobsonion designs, so whatever your viewing preference they will have you covered, remember you are paying for the app, not the quality of the equipment. So for a beginner or returning hobbyist I think this is a great jumping off point and a gateway into bigger and better scopes down the line. Grab this scope, upgrade those eyepieces, download that app and have hours and hours of fun. I would like to see Celestron come out with a universal StarSense phone mount and then allow you to pay for the app, I would love to have this on my dob, maybe some day. Happy stargazing!! ... show more

    • Good backyard scope
Style: StarSense Explorer DX 102
I bought the 102 mm refractor for backyard planet watching. I wanted the larges aperture that I could easily carry out the door, set up, and get on target. I didn't want to have to fuss with collimation, or wait for cool-down, so a refractor seemed like a good choice. I also wanted dual slow motion controllers. This scope fit all of the bills, and I think it was a good choice. One thing to keep in mind that this is a short focal length refractor, so at high magnification bright objects will generate significant chromatic aberration- you'll see purple and yellow halos. Celestron has pretty cleverly provided for this- the lens cap has a central hole of about 50 mm with a second small cap on it. If you want to look at something and are bothered by chromatic aberration, pop the cap on with the center hole open. It will reduce the amount of light coming in (and resolution, a bit) but it nicely tames the chromatic aberration. The red dot finder works extremely well for getting lined up quickly on bright objects. I haven't had time to play with star sense yet, but even without it this is a nice scope and it meets my needs perfectly. Edit: After I got this scope, I tried using the Star Sense cell phone holder. My first time out with it, I dropped it and it broke. I contacted Celestron, and they shipped me another. Great customer service! Now that I've had a chance to use, I have to say it's pretty impressive. It works well, and makes it possible to find things that I couldn't otherwise. All in all this is a great scope and exactly what I wanted. ... show more

    • starsense doesn't work in light polluted citys
Style: StarSense Explorer DX 102
the OTA is fine for the money, the mount it's ok at best, a bit stiff and a bit shaky at high magnification but the slow motion controls are a nice feature at this price point what really sucks it's that the starsense technology doesn't work at all in light polluted skys, I live in Monterrey, México, an 8 million people city so there's a lot of light at night an the starsense can not locate itself, I've tried everything, pointing it to different parts of the sky and in some rare cases it locates itself but as soon as you point the telescope to a target, it looses itself, so it renders the technology complety useless ... show more
