Description
Night Sky Tools is the ultimate collection ofastronomical tools perfect for anyone interested inastronomy.
The calculations are of a high enough accuracy for almost allamateur astronomy applications.
Due to the fact that astronomy is often best when far fromcivilization where mobile signal may not always be reliable.Therefore, this app is (almost) completely self-contained and doesnot require any internet connection for most of the informationavailable. The only exceptions to this are the SOHO solar imagesand NGC/IC, Messier, Caldwell and Binary star images and weatherforecast which are loaded dynamically, as well as the refreshing ofsatellite, comet and near-earth asteroid data.
Night mode turns the display red for night observations withouthaving to ruin your night vision.
The Sky Map makes use of the direction sensors of the device toshow the sky above (or below you). Most of the features can betoggled in the settings. The Sky Map also allows you to turn on thedevice's camera to see the view behind the device with the sky mapsuperimposed over it.
The direction sensors of the device may need to be calibrated ifthe map appears to be pointing in the wrong direction. To calibratethe device's sensors wave the device in a figure-8 pattern. If thedirection is still off, then the direction calibration can beadjusted manually by changing the setting in the Settingsscreen.
The observation log, allows you to save observations in theapplications, as well as manage a list of astronomical equipmentand observing locations. This equipment is also available for usein the Telescope Calculator.
Most of the data screens have an option to share the data viaemail, or other similar apps able to accept HTML content.
The Astronomical Time is also available as a Home screen widget. Touse the widget, the app needs to be installed onto the internalstorage instead of the SD card, otherwise it will not beavailable.
Some permissions are required for correct functioning of theapp:
Location - used to determine user location throughout the app
Camera/Microphone - used to allow camera background in skymap. Themicrophone is never used but this permission is bundled withcamera.
Photos/Media/Files - used to allow proper functioning of the fullscreen images and caching of images
Network access - used to do online searches, and downloading comet,asteroid and satellite data, object images and geocoding.
The app is jam-packed with features:
- Observe the sky with the skymap, planisphere, aurora forecast,polar finder, weather forecast, daylight map, Moon and Mars maps,SOHO images, Jupiter and Saturn's moons, Moon and Sun calendars andwhat's up.
- Detailed object information on the planets, constellations,comets, exoplanets, meteor showers, near-earth asteroids,satellites, as well as the full NGCIC, Caldwell, Messier, 6thcatalog of Visual Binary Stars by the USNO and General Catalog ofVariable Stars catalogs, as well as a SIMBAD search.
- Calculate angular separation, atmospheric refraction, magnitude,coordinate conversions, visual limiting magnitude, precession,redshift, and telescope airy disc, f-ratio and magnification
- Astronomical references, glossary, HR diagram and stellarclassification.
- Astrophotography tools for exposure time, CCD resolution,Untracked exposure time and optimal f-ratio.
- Emphemerides for eclipses, equinoxes, conjunctions andoppositions, the sun, moon and planets
- Observation log
- Astronomical time
Caller ID
Night Sky Tools has free caller ID. It identifies callers for you -even the ones not in your contact list. Caller ID results are shownafter calls and also allow you to save the contact details directlyto your address-book. You can disable or adjust caller ID to yourpreferences in the app menu settings or after-call screen settingsat any time.
