As the first telescope that utilises your smartphone for real-time night sky analysis and positioning, the Celestron StarSense Explorer is an exciting new prospect for those looking to take their first steps into stargazing. It works through the StarSense Explorer app, which auto-generates visible points of interest and directs you towards them. When the telescope has been manually aligned, the bullseye will turn green - allowing you to look through the eyepiece and gaze at planets, brighter nebulae and galaxies, and even some star clusters. Classified as a Schmidt-Cassegrain telescope system, you are granted a 12cm (5"") optical tube consisting of key StarBright XLT coatings. The manual altazimuth mount further provides smooth, dual-axis slow-mo control as you navigate the night sky and discover distant points of interest. This specific system is compatible with an iPhone 6 and up, as well as Android 7.1.2 or later (since 2016).
