EZ PUSH vs Planet Fun

EZ PUSH TO is a sky map app running precisely when the Bluetooth encoders on GSO Dobsonian is connected. Without encoders, the app still works relying on iPhone's compass and gravity sensor. EZ PUSH TO is designed for visual astronomy. The star map assists you browsing the real sky. The map is concise, but completed with Messier/NGC /Herschel catalogue, double and binary stars, comets and asteroids, and magnitude 10.5 stars (270K stars) for general purpose. EZ PUSH TO features lots amazing interface, such as lazy "roaming" in the deep sky, and "Messier marathon" to enhance your stargazing skills. It absolutely brings you and telescope freely to reach the real deep sky at your backyard, or in your family camping.

PlanetFun is a 4D solar system simulation (3D + time) Sun, planets, Moon and star positions are calculated using various astronomical methods. App source code (Delphi Firemonkey) is available at: https://github.com/omarreis/vsop2013 PlanetFun features: * Solar system animation with configurable speed * Set any local date and time * Choose camera target (Sun, planets, etc) * Configurable camera distance-to-target * Touch gestures: one finger pan, two finger zoom, two finger rotation * show planet orbits. Each orbit is represented by 52 dots (for Earth it is one dot per week) * Heliocentric axis (x and z) * VSOP2013 and VSOP87 planet position calculations * Moon positions calculations ELP2000 * Star background image with 42455 stars of the Hipparcos Input Catalogue * Star and constellation lines and names ( a celestial sphere image ) * Constellation drawings ( 31 constellations ) * actual 3D spheres for the 150 brightest stars * Lighthouse on Earth on your GPS position * phone in the scene is positioned according to phone sensors (Azimuth,Elevation,Roll) * click the phone button to enter augmented reality mode. * Almanac module allows exploring the ephemeris calculators (stars, planets, Sun, Moon, Earth) controls: * camera distance and angle of view. * planet scales * local time, time animation speed * control visibility of various interface elements * app uses sensors compass, gyro and GPS - requires permission This app collects no user data.
