The StarSense Explorer LT 70AZ is a 70mm refractor on an alt-azimuth mount that uses your smartphone to find objects in the sky. You dock the phone, run the StarSense Explorer app, and after a short alignment it points you to planets, the Moon and bright deep-sky targets. It suits first-time stargazers and families who want guided finding without learning star charts, and it is simpler to set up than a computerized GoTo mount, though its 70mm aperture limits faint objects compared with larger reflectors. Owners rate it highly for ease of use and the app-guided pointing.

Owners rate it very highly, praising how the app-guided pointing makes finding objects easy for beginners. The main reservations are the modest 70mm aperture and the basic mount and tripod.
The Celestron StarSense Explorer LT 70AZ is a manual refractor telescope that works with a smartphone to guide you to objects in the night sky. You place your phone in the StarSense dock and launch the StarSense Explorer app. After a 2-minute alignment using the phone's camera and the telescope's optics, the app lists the objects that are currently visible.
Pick a target and on-screen arrows show you how to move the telescope. When the object is centered, the bullseye indicator turns green. The app uses StarSense sky recognition technology, which analyzes star patterns to work out where the telescope is pointing. It does not rely only on gyros and accelerometers.
The telescope has a 70mm refractor tube with fully coated glass optics. The manual altazimuth mount has an altitude slow-motion adjustment with a sliding rod, and it sits on a full-height adjustable aluminum tripod. The included 90-degree erect image diagonal also lets you use it in the daytime to view birds, wildlife and landscapes.
