And that’s the advantage; you do not have to fulfill your harddisk with application, beside high resolution image.
Google sky use equatorial coordinate system. At this system, sky objects shown by two numbers, ascensiorecta (English: right accession or RA), and declination. RA number shown in format that same as time format (hours minutes second), while declination shown in angle format (degree minutes second). You don’t have to confuse, if you know object that you wanna see, just typing it in search box.
Sky objects also have electromagnetic light radiation which cannot see by eyes, like infra red, radio wave, and others. Google Sky appears visualize that radiation.
