Celestron LT 70AZ StarSense Explorer Telescope

Further details

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. This technology makes stargazing with an affordable telescope simple and rewarding, just add your smartphone and let it search for you.

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. F

StarSense Sky Recognition Technology
StarSense Explorer uses patent-pending 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 reorient 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.

Sturdy Altazimuth Mount
StarSense Explorer LT’s simple altazimuth mount makes it easy to move the telescope to find your target. A slow-motion altitude adjustment knob helps you fine tune the telescope’s pointing position and follow targets as they appear to drift across the night sky. It’s all anchored by an adjustable, full-height tripod.

Dazzling Views with High Quality Optics
You can expect sharp, bright views through this 70mm refractor. Fully coated glass optics provide increased light transmission, enhancing details in celestial objects. The telescope also includes a 90-degree erect image diagonal, so you can use it during the day to view birds, wildlife, landscapes, and more.


Perfect for the City or Dark Sky Sites
Even if you live in a light polluted city location, StarSense Explorer is advanced enough to be able to pick out Jupiter, Saturn, Venus, the Orion Nebula, double stars, and a few more of the most famous celestial objects.

But if you can take the telescope to an even slightly darker location, more objects will become visible. The entire telescope kit weighs just 7.4 pounds, so it’s perfectly portable and easy to bring on your next camping trip or to a remote observing site.

  Fast delivery  This was a present for my 30 year old granddaughter she is totally over the MOON with it first class she says  (18/09/2024) David - East midlands

  Good introduction telescope   Bought this for my grandson as an introduction into astronomy. The scope itself has an all aluminum tube a workable focuser that is up to task. The tripod although being all aluminum is well made and is also up to the job. Optically decent although I upgraded the diagonal to one of my own.  (28/06/2022) Ian Sykes - Oxford

  Star sense explorer.  Great telescope, my daughter loves. great value and service from Harrison's also.  (07/03/2022) Luke Bendall - Brighton

  Fab telescope for a beginner  We bought this for our sons 13th birthday and did quite a bit of research into the best telescope for a beginner. The StarSense did not disappoint. We were able to put it together easily, download the app, attach the phone and he was off. He has used it every clear night so far and loves it!  (29/08/2021) Lucie - London
