Night Sky Tools - Astronomy« Travel & Local « Downloads

This app is a collection of astronomical tools and charts perfect for anyone interested in astronomy. The calculations are of a high enough accuracy for almost all amateur astronomy applications.
Due to the fact that astronomy is often best when far from civilization where mobile signal may not always be reliable. Therefore, this app is (almost) completely self-contained and does not require any internet connection for most of the information available. The only exceptions to this are the SOHO solar images and NGC/IC, Messier, Caldwell and Binary star images and weather forecast which are loaded dynamically, as well as the refreshing of satellite, comet and near-earth asteroid data.
The observation log, allows you to save observations in the applications, as well as manage a list of astronomical equipment and observing locations. This equipment is also available for use in the Telescope Calculator.
Night mode turns the display red for night observations without having to ruin your night vision.
Most of the data screens have an option to share the data via email, or other similar apps able to accept HTML content.
When using Android 4.0+, the Upcoming Events is able to add events to the device’s calendar by using a long click.
The Astronomical Time is also available as a Home screen widget. To use the widget, the app needs to be installed onto the internal storage instead of the SD card, otherwise it will not be available.
Android 2.2+ is now supported, but Android 4.0+ to get the full user experience.
The direction sensors of the device may need to be calibrated if the map appears to be pointing in the wrong direction. To calibrate the device’s sensors wave the device in a figure-8 pattern.
If the direction is still off, then the direction calibration can be adjusted manually by changing the setting in the Settings screen.
