My hobby is astronomy, as I find out the evening just before the construction of my telescope on the current starry sky. After a short settling in the menus, you can quickly have a nice overview of Constellations, Planets, star clusters, nebulae and similarly important. You can rewind before and also nice time, one chooses for example a time of observation of the moon and watch the walking and change through the Zodiac during fast forward the date.
