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.

    • Stary nights
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.

    • 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

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.

I could see all the craters with perfect detail. Very easy maneuver for the moon, takes time to get the planets.

    • 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

The star finder has not worked since purchasing. We waited a while to try it before realizing it didn’t work. It is hard to find anything without that piece. We will have to spend another 30 for the piece to get it to even work

Totally amazing beginner telescope. Son’s 19th bday present. Good size, excellent app to assist, loads of fun. It’s a good size but light and easy to move around. I’d recommend a case at some point

    • Good value for the price, but you get what you pay for
Style: StarSense Explorer LT 80
This is a good value for the price, and the app makes finding stars super easy. However, the build quality is kinda flimsy and it never really stays locked when you tighten the traverse and elevation screws. Even with everything tightened there’s a lot of wobble and shake to it, which makes focusing on things harder than it should. For the price it’s a fair value, but if you’re looking for something with a higher build quality you’ll probably be better off buying a better model. ... show more
