The display includes up to 100 million stars, 13,000 deep-sky objects,all 8 planets, the Sun and Moon, and thousands of comets, asteroids, supernovae, and satellites. It provides an accurate graphical simulation of the night sky, from any location on Earth, at any date and time. The last lines show you who to turn the knobs on your mount.KStars is free, open source, cross-platform Astronomy Software. Now click on the label to retrieve the information details. Next, click on the object you want to observe. To find these, first click the object on the chart to which your telescope is pointed. Otherwise, leave it unchecked.įrom now on, you can find instructions how to turn the knobs of your mount to move from one object to another. Only when a counter-clockwise turn of a knob causes an increase in the right ascension, azimuth, declination, or altitude, you need to check the appropriate Reverse. When you know the number of tooths, calculation of the number of turns per degree of arc, or per hour is easy: Per degree: 144 / 360 = 0.4 Per hour: 144 / 24 = 6Īlso you need the find out how to make the direction setttings for the knobs. Most common is a mount with 144 tooths on the worm wheel for both directions. Usually, manual mounts are wormgear driven. Next, you set how many full turns you must make on your knob to slew your mount by one degree of arc. Choose your mount type from Equatorial Mount or Alt/Az Mount. When you use this, Sk圜hart asks you to give the settings for your specific mount. If you use Windows XP, copy the file libmySQL.dll from the bin directory of your MySQL installation to the installation directory of Skychart. Another warning: When you decide to load the data from MPCORB without any limitation into your MySQL DBMS, it can take some hours. You need to have at least basic knowledge about MySQL to do your queries. Or you want to share one single database with many computers. For example, maybe you wish to search comet and asteroid data external from Skychart, with other applications. Maybe you have reason to choose MySQL as DBMS. SQLite is very fast and for everyone simple to use. You can create them by Configuration → Observatory.Ī standard Sk圜hart installation creates a SQLite database. The information about countries and the detailed information of Observatory locations are also stored in a database. For more about installing and downloading SAC pictures, see the Object tab from the Configuration → Pictures dialog box. You may also want to create the SAC pictures information database. See the comet and asteroid tabs from the Setup → Solar System dialog box. But before Sk圜hart can do that, you need to download fresh files with orbital elements for comets and asteroids. In order to display comets and asteroids, Sk圜hart needs to calculate the ephemeris, and store them in a database. It contains the orbital elements of comets and asteroids, SAC picture information, information about the DSS/RealSky pictures and information of observatory locations. In this window, you can manage the Sk圜hart database.
