Please check out www.ezCelestial.com for a full description of the application and in-app help pages. Universal app! Use on iPhone, iPod Touch and iPad! ezSights has been tested and proven to be fully compatible with both iOS7 and iOS8.ezSights is a complete celestial navigation package for the iPhone®, iPod touch® and iPad®. It provides simple interfaces for entering sight parameters, planning the navigational bodies to use and time of day to make the observations, and entering the observations made using a sextant. Then with the click of a button a fix is determined from the observations made. Features ▪ Internally calculated Nautical Almanac values, valid through 2060. ▪ Performs all calculations with same algorithms used by the US Naval Observatory for the Nautical Almanac. ▪ Supports all navigational bodies currently referenced in the Nautical Almanac. ▪ Computes rise and set times for the sun and moon. ▪ Computes moon phase, HP, parallax and semi-diameter. ▪ Animated star map to aid in locating and identifying all navigational bodies. ▪ Display of full day, morning, or evening altitude profiles for all navigational bodies. ▪ Save current data and up to 7 previous fixes. Each session can have up to 25 observations on up to 3 navigational bodies. ▪ Supports running fixes. ▪ 2 different methods for determining a fix. ▪ Supports practice sights using a bubble horizon, artificial horizon, or large body of water using dip short. ▪ Integration with iOS® Maps to display saved fixes. Also supports setting the assumed position by dropping a pin on the map. ▪ Integration with iOS® location services to obtain position and magnetic variance. ▪ Integration with iOS® devices with compass for direction-up display of the star map and to show azimuth of object currently being observed. ▪ Integration with iOS® data network for setting UTC time from network time using NTP servers.
