Night Vision

Night Vision is a "planetarium" program for OS/2, and will display the heavens from any location on earth. Viewing options allow the user to control which sky objects to display, which font to use, and manipulation of various star parameters. Time may be set to run at multiple speeds, including backwards. Star charts may be printed.

Moving the vertical scroll bar (right side of window) controls the altitude, or the angle from the horizon to the center of the view (center of window). With the scroll at the top the view is straight up (the zenith). Moving the scroll to the middle shows the view along the horizon, and moving it to the bottom shows the view through the earth (the nadir). Tinting will indicate where the earth blocks the view. (This horizon indication can be turned off.)

Moving the horizontal scroll bar (bottom of window) controls the azimuth, or direction along the horizon. With the scroll in the center, the view towards the horizon is to the south. Moving the scroll to the right moves the view to the west, then the north. Moving the scroll to the left moves the view to the east, then the north. Thus north can be achieved by moving the scroll either to the far right or the far left.
