The difference with this one, which I quite like, is the "low distortion" idea - it better represents what the eye sees, which is particularly useful when learning the constellations.
My only complaint - I wish the South facing view was the larger, as there are more interesting things to see in that direction.Great for Planning a Night of Viewing Even though the Night Sky chart is primarily of use to novices, intermediate and advanced viewers will find it useful for planning a night's viewing activity, primarily determining what objects are visible at what time. This kind of information is not easy to get directly from star charts. With a customized, time ordered checklist and a computerized telescope (plus good conditions), it's easily possible to view over 100 objects in a few hours.
