With the recent update, the ability to use any place and time makes this a keeper. A few tweaks and this would be a 5-star application. The Place/time selection is rather cumbersome - a map/crosshair arrangement or even the ability to type in Lat/Long would be an improvement over the silly iPhone spinning wheels. When you change locations via Lat/Long, the time selection creates questions. Is it Zone Time, LMST, DST etc.? Some clarification here would be nice. Some star data seems to be missing (Beta Crux, Gamma Crux for example) and crosshair selection on the Sun and Moon leading to Rise/Set/Phase/Transit data would be nice. But these are all wish-list items that would make a very good planetarium application into a great one.
