Is it any good?
STARMAP HD is a comprehensive sky atlas with catalogs and maps of 2.5 million different astral bodies including constellations, planets, and comets. When a location is entered, the app calibrates a starchart with nearby points of interest that should be visible that night. There's an exhaustive amount of information and detail here -- including useful tools like a log book, compass, night vision mode, and Telrad finder -- that make this app a great resource for serious amateurs with telescopes. It's also fairly accessible to casual stargazers old enough to understand how to operate the app's multiple functions.
