Native OS X app written in Swift 3 and built with XCode. Utilizes location services and the calculation featured at the USNO to compute the Right Ascension and Declination of the zenith at current user location, which is fed into the Sloan Digital Sky Survey's DR13 Finding Chart Tool to return the image at the correct dimensions then used to set the desktop wallpaper.
Users at certain locations may experience perodic outages in sky survey images as the RA's (changes with time) corresponding DEC (fixed to the longitude of the user's position) at zenith may be out of the SDSS's recorded range.
