StarSense Explorer DX 102AZ is perfect for beginners with its user-friendly interface and detailed tutorials, serving as your personal night sky tour guide. The included EclipSmart Solar Filter ensures you're prepared for both Sun viewing and the upcoming 2024 Total Solar Eclipse; it's custom-designed to fit this telescope securely with three safety screws. EclipSmart solar products feature Solar Safe filter technology and has been independently tested to conform and meet the transmission requirements of ISO 12312-2:2015(E), Filters for Direct Observation of the Sun. StarSense Explorer is the only telescope that uses patented sky-recognition technology and your smartphone for real-time sky analysis and positioning. 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. 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 move the telescope. When the object is ready to view, the bullseye turns green. 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. StarSense Explorer technology determines 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 orient 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.
