The Earth Centered Universe

 ECU V1.4 is a shareware Sky Visualization Program for Microsoft 
 Windows 3.x called "The Earth Centered Universe".  It is capable of 
 simulating many of the features of the Earth's sky.  You only need to 
 enter your geographic location and the time and the local sky is
 simulated on the screen in a colourful display.  This includes, but 
 is not  limited to the stars, planets, Sun, Moon, and "deep sky" objects. 
 Constellation, coordinate grid, ecliptic, and local horizon lines are 
 also displayed.  ECU is designed as an observing tool for the observing 
 amateur astronomer, but is equally useful to the "armchair" astronomer 
 or other interested person interested in the night sky.
