The Celestron StarSense Explorer DX 102AZ offers access to the myriad targets that grace our night sky, but can be tricky to locate if the astronomer is just starting out in skywatching. The instrument is computerized, making use of the observer's smartphone and free-to-download StarSense Explorer app to make navigating the night sky and exploring solar system and bright deep-sky objects such as nebulas, star clusters and galaxies fun and, above all, a breeze to find. 
The initial advent of computerized star catalogs, which were loaded into telescope handsets, made it possible to align a telescope on the sky by pointing it at just three bright stars. Once done, the handset was able to direct the telescope to any other object in its database, but it needed position encoders on its axes. All of this requires some user input — namely the date and time, the location, and choosing the stars.
