Description

Celestron’s StarSense Explorer LT 80AZ is the first telescope that uses your smartphone to analyze the night sky and calculate its position in real time, making stargazing easier than ever. Perfect for beginners, this app-enabled telescope lets you dock your phone, launch the app, and follow on-screen arrows to planets, stars, galaxies, and more. Unlike other astronomy apps that rely solely on gyroscopes, StarSense uses patented sky recognition technology and a Lost in Space Algorithm (LISA)—like the sophisticated location systems used by satellites—to deliver accurate, real-time guidance. Simply align your phone with the telescope optics, and within minutes, you’ll be exploring with confidence. The app automatically generates a list of the best objects to view based on your exact time and location. Choose one and navigate there by following the on-screen arrows. When the bullseye turns green, your target is ready in the eyepiece. The high-quality 80mm Refractor with highly reflective coatings provides bright, detailed views of the Moon, Jupiter, Saturn, Mars, and deep-sky favorites like the Orion Nebula and Andromeda Galaxy. Includes two eyepieces (10mm and 25mm), an erect image diagonal, a red dot finderscope, a full-height tripod, and a StarSense smartphone dock. StarSense Explorer works with most modern smartphones; it is compatible with Android 12 and later, as well as iOS 18 and newer, including iPhone XR and newer models.

    • Excellent 1st telescope
Style: StarSense Explorer LT 80
This is a great first telescope for anyone interested in starting astronomy. It is light weight so you can travel and carry it easily. Easy to assemble with the manual and I am not that mechanically inclined. There are a few videos on YouTube of unboxing and assembly. It gives an excellent view of the moon. You can see the craters and mountains with the 25mm and 10mm eyepieces. As far as the planets Jupiter and Saturn you can see the moons of Jupiter very clear with the 25mm, but you won't be able to see the bands around Jupiter. It looks like a big bright star. But still very impressive. With the 10mm eyepiece you can somewhat make out the bands. Saturn you can see the ring. I would suggest getting another high powered eye piece with a wide field of view because of the low field of view the planets drift fairly fast because of the earth's rotation. Star clusters come in great! Pleiades and Caldwell 13 are beautiful! For a beginning star gazer or someone not wanting to spend a lot of money this is a wonderful first telescope. ... show more

Style: StarSense Explorer LT 80
OMG, I bought this for my husband for Christmas and we all love it. It’s the families gift. You could see the stars and planets very clearly, it’s comfortable to use. It seems very professional from my perspective definitely worth the money.

    • MUST HAVE if you have never worked with telescopes before....
Style: StarSense Explorer LT 80
I am not sure why there are many complaints about the telescope and not able to see objects properly or in some at all. The first thing that you need to do is tune it well and after that never go directly using the 10 mm lens with the Barlow lens. Start with the 25 mm then go to the 10 mm and then use the Barlow lens focusing on the object with each initial view. Also understand that when focusing on planets, the planet might go out of the captured area because our planet is rotating on its axis too so keep on tracking how the planet you're viewing is moving in the sky relative to your position. If you end up to the most zoom using the 10mm and Barlow Lens you will notice the planet quickly move up or down depending on where you are. so move the telescope accordingly. Also, make sure that your telescope is held at a firm surface, slight vibrations can make you lose focus. There is a lot of learning you can do with this telescope that can help you use more expensive telescopes. My plan is to get more lenses in the future and work with this telescope for a few years and then buy a more expensive telescope with the tracking motor. I am very happy with this purchase and would suggest anyone to buy this as a starter. I have not used the StarSense app yet, it is very finicky, and use my own sky view app to track objects in the sky. That would be the only negative I have but that can be fixed if they make app updates. ... show more

This telescope is good for its price and very sturdy. With its ease of use and clarity, it’s nice for beginners and intermediate astronomers. It was very easy to set up and use. The app didn’t work well for us. We were able to eye it and get a picture of Jupiter.

    • Good product. Thank you.
Style: StarSense Explorer LT 80
The telescope is excellent for observing the moon. And some planets. It's my first telescope. And it's easy to use. To be for the first time. I recommend it. Especially. For beginners. The app is shareable with any phone.

    • Not user friendly; difficult to see anything
Style: StarSense Explorer LT 80
Very difficult to set up. I even watched the YouTube videos. Also, YouTube reviews/setups. When you have to synch with iPhone which best to do in daylight, then you cannot remove your smartphone to keep it synched. Or, you have to do the process all over again. That's ridiculous! So from late afternoon to late evening, I cannot use my phone? After 5 months, I've yet to see even the moon. I have had better luck just looking up at the sky. I even tried to use the telescope without the smartphone, but nope - nada. I switched out lenses. Nothing. When I purchased in the beginning of the summer, I tried to use it at night a couple of times and got mauled by bugs. So I figured I would try again in the Fall, especially after the first freeze. Last night (11/6), I went out because it was a beautiful dark night sky and I can see Mars right above my house. All I saw was blackness in the scope. And, yes, I did remove the lens caps. The only thing I can say is unless you have an extra smartphone to leave connected (and outside) with the telescope, you can forget about using the smartphone tracking feature. Even though I live in the suburbs (outskirt of city area), we get some really good night sky vistas of Mars, Saturn, Jupiter. I've even been able to track the space station across the sky. Just by looking up (for free). So, unfortunately, I am out about $180 (after taxes); but more importantly, I am extremely disappointed. ... show more

    • Received with broken part although listed new
Style: StarSense Explorer LT 80
The telescope itself is really good, can see in awesome detail. The app part isnt ideal for my type of phone, it doesnt turn the camera on consistently and the position is off a bit. Scope works great. Giving purchase rating only a 2 because the item was listed new but was received used and the altitude rod was broken when received. Very disappointing since I paid a higher price than other listings, because it was a gift and I needed new. ... show more

    • Great starter telescope-must have!
Style: StarSense Explorer LT 80
Love this scope. We are new to using a telescope and so glad I purchased this one to learn from. We have already spent hours outside just looking at the night sky! We did purchase an upgraded lens (Celestron X-cel) but the lenses that come with it are not bad either- especially if you are starting out. We used the included Iphone app download to locate planets (Saturn, Jupiter) and other constellations. The images are clear and so wonderful. You can see the rings of Saturn and Titan when conditions are good-although Titan is a little bright dot but still exciting to see. Seeing Jupiter's 4 moons and the colors is just so fascinating. The moon was absolutely beautiful to see- very detailed. We purchased some filters as well- the moon filter really helps and the blue filter is great when looking at Saturn and Jupiter. We are still learning and we have the bug- wanting a bigger telescope already but will definitely continue to learn our way around the sky with this one! The telescope arrived a day earlier than expected and no issues- packaged great- no damage. Easy to set up. If you're new to observing the sky as we are- I would suggest some great books to accompany the telescope- also sold on Amazon to assist with educating yourself on the world of astronomy. Very happy with this purchase and would recommend it to anyone! ... show more
