Sky Atlas v1.31 for Android

This list of items is not directly related to the star chart, but to astronomical time-keeping, information and visualizations.The use of Sky Atlas is believed to be simple, intuitive and largely self-explanatory, yet requiring basic knowledge of astronomy and familiarity with your Android phone.Sky Atlas is not planetarium or simulation software. It is designed analog to a paper atlas for the purpose of looking up sky positions of celestial objects. The electronic form takes advantage of zooming and selection of objects to be displayed or not -- possibilities which are not available to paper. The star chart is plotted on equatorial coordinates. Current horizontal positions, rise & set times, etc. for objects can be viewed after selection of an object of interest. A star chart can be saved to external memory card for documentation purposes, such as websites or blogs.
