FAQs and Tips 　 　 　 　 　 Q. How do I change the Observation time? The programming for time must be set in Normal Mode. When the Real Time Mode is set, the display on the screen is based on the current time, (you can not change the time). You must change the Real Time Mode into Normal Mode in the time setting dialog. Q. Auto Mode is not working Auto mode does not work when you set real time mode ON. Real time mode displays sky based on the current time. You must disable real time mode in order to use auto mode in the time setting dialog. Q. It looks different from the actual sky view Please check the observation point and the observation time again. Planetarium displays a very accurate sky map except for a very minor error in sun, moon, and planets' relative positions. Q. The screen does not move by pressing the arrow Up key You are probably looking directly above yourself and you can not look up anymore. Q. Screen does not move by pressing arrow down key You are probably looking at the horizon line and you cannot see below the line. The Program can display stars below the horizon line, but you can not see them in a real setting. Q. Dark stars are not displayed You may need to increase your monitor's brightness, or darken your room to see a darker sky. You may also change the display options to improve the view by hitting the B key. Q. It takes too long time to display anything You must decrease the number of stars you display because your CPU is not running fast enough for a lot of stars. To do this, press Shift + B. Q. I do not know how to set real time display mode. The time programming option can be set to be real time which displays the current sky as it appears at the current time, and the screen is updated as time passes. Q. Names overlap and I can not read them. You may need to display only the names you need, or zoom in to see the object that you are interested in. If you place the mouse cursor on the object and wait, you can display the object's detailed information. The maximum zoom-in ratio is 7700%. Q. When I try to launch the program, I get a loading error and Planetarium does not start up. We recommend that you reinstall Planetarium. You can simply delete the folder where you saved Planetarium and place the CD in the CD drive again. It will start the installation process automatically. Q. Interval in Auto Mode changes around. The Interval is set for the end of one display to the beginning of the next display. Therefore, depending on the number of stars and your CPU speed, it may take more time to update the display screen for the next time step. Q. I'm having a problem printing correctly. Please check your printer settings and cables. If it does not print anything, you may try to print something else from another program to test it. Q. How can I add a new comet? In order to add a comet, you'll need some detailed information (parameters for orbit). They can be found in astronomy publications or on an Internet site for the comet you are interested in. Q. Can I use the screen shots, or printed screen for my own use? You can use screen shots or printed graphics for non-profit private or educational use. You must, however, indicate that they are from the Planetarium program. Q. The dialog disappeared and the program froze. What should I do? When an active dialog is behind the solar window, it seems like the program does not respond. Please move the solar window, or minimize it so that you can see the active dialog. Q. What is the Horizon Coordinate mode? The Horizon Coordinate mode is a system of spatial reference that uses the Earth's horizon line as it appears from the location currently active. In this mode, the horizon from the current location is 0°. This is the best mode for beginners, because if you choose your own home city as your location, and then look outside, you should see the sky (barring any environmental factors such as clouds, light etc.) exactly as it appears on the screen. Q. What is the Equator coordinate mode? The Equator coordinate system uses either the Earth's Equator or the Celestial Latitude (or the plane perpendicular to the axis point of the sun) as 0 degrees. This is an absolute system, in other words, this system is the same no matter where you are viewing from. This is used by astronomers as a spatial reference system. Q. What is the difference between the ecliptic and Equator Mode coordinate systems? In the Ecliptic mode, Latitude is measured north and south of the ecliptic, or plane perpendicular to the axis point of the sun. In comparison, the Equator Mode uses the Earth's own equator as it's point of origin, or 0 degrees Latitude/Longitude. 　 　 　 　 　 　 　 　 Patches 　 　 　 　 　 • Product Registration: 　 Click Here 　 　 • Tryout Version is available at "Free" section of the following link. 　 Click Here 　 　 • Upgrade Version is available.
