- Description of SkyView
- ======================
-
- SkyView is one of a growing number of astronomy applications for
- Microsoft Windows. The program is designed to perform many of the
- functions of a planetarium. As the name suggests, SkyView shows you
- a view of the sky. The whole sky. It shows everything that you can
- see in the sky from one location at one time.
-
- SkyView displays
-
- o The positions of the sun, moon, and all planets visible with the
- naked eye.
- o All stars down to a limiting magnitude you select.
- o The positions of the ecliptic, celestial equator, galactic
- equator, and equatorial coordinate system lines in any
- combination.
-
- SkyView allows you to
-
- o See the sky as it looked or will look at any date and time
- between the years 1900 and 2100, inclusive.
- o See the sky as it looks from any location on the earth.
- o Orient the sky display so that the North, South, East, or West
- horizon is positioned at the bottom of the window.
- o Print and print preview the sky display.
- o Select the colors used for the window background and many of the
- objects in the sky display.
-
- SkyView was developed with a limited goal in mind. It does not try
- to do everything and display everything related to astronomy.
- SkyView is not the fastest program, and it is not the most accurate.
- SkyView does not display small sections of the sky filled with dim
- stars that you can only see through binoculars or a telescope. It
- does not display deep sky objects such as nebulae, star clusters, or
- galaxies. It does not label constellations or individual stars.
-
- SkyView is free. If you enjoy playing around with it, that's great.
- If not, let me know why.

- Software and Hardware Requirements
- ==================================
-
-
- Software Requirements
- ---------------------
-
- SkyView requires Microsoft Windows 3.1, running in 386 Enhanced Mode.
-
-
- Hardware Requirements
- ---------------------
-
- For the best performance, SkyView should be run on a computer
- equiped with at least a 486 CPU. Not only are such computer fast,
- they are all equiped with a math coprocessor. Computers equiped with
- 486SX and 386 CPUs may contain an optional math coprocessor chip,
- but many do not. SkyView performs very many trigonometric
- calculations to generate the sky display, and these calculations
- take significantly longer to perform without a math coprocessor. A
- sky display that takes seconds to generate on a 486 system will take
- minutes on a 386 system without a math coprocessor.
-
- SkyView requires that you run Windows in a video mode that can
- display 256 colors. It will run in a 16-color video mode, but the
- sky display won't look very good. I've made no attempt to write the
- program for or test it in a 16-color video mode. Hey, this is 1993.
- Decent hardware is pretty cheap.
-
- SkyView requires 800KB of hard disk space.
