Dennis Allen Freeware
SAC v4.00 (beta)
The Foxpro SAC System is a set of programs designed to record and track the Saguaro Astronomy Club Database. This application includes the SAC deep-sky v7.2 and double star v2.1 databases, some SAC variable stars, a set of star charts generated by The_Sky for windows (Software Bisque) and a Moon database created from U.S. Geological Survey listings. There is also a celestial database that lets you keep track of comets and asteroids.
Among the SAC System features is the ability to access records by object name, type, constellation, celestial location or by notes. You can keep user logs and attach images. If you're using Visual Foxpro, you can link an object directly to The_Sky for windows. If you are connected to the Internet, the Visual Foxpro version will also let you display Digital Sky Survey images and Bowker/Hughes Lunar photo atlas images.
