Sky Atlas

【免費書籍App】Sky Atlas-APP點子

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.

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.

Atlas Objects

Opens a list of object categories. Tap on a category to view available objects. Upon selection of an object, its data is shown in a message box, from which to return to selection of another object or choose to center an object on the star chart. Categories which contain a large number of objects are assigned a sub-menu (tap on screen's menu button) which allow to narrow down by various criteria dependent on the nature of the category.
