In three parts this two volume set will perform the most common astronomical calculations,provide data on objects in the solar system and search a sky catalog of over 2000 deep sky objects, the Messier Catalog, 100 named objects,all bright stars to MAG 2.00 and more. Objects may be searched by one or more criterion. For example the catalog may be searched for all double stars or just the ones in a section of the sky. All three programs are menu driven and a detailed 32 page users manual (ACE.doc)is provided on the first volume. The first program Acecalc.com, is a menu driven Astronomical Ephemeris. In the menu mode it reads the clock and converts the local time to G.M.T, Mean Sidereal time and Julian day.By selecting an option from the menu one may find data on the position of the sun, Moon,and planets for a selected time and day.This program will also calculate astrophotography exposures,Sidereal time, precession of coordinates, phases of the Moon, Equinoxes and Solstices, Galilean satellites of Jupiter, print a perpetual calendar, give the low down on polaris and execute DOS commands without leaving Acecalc. Neat. No sky junkey should be without one. The second program is Acesolar. This program provides reference data and comments on objects in the solar system and plays a tune fitting the object selected. The music may be turned off. The third program is Acecat. This is a sky catalog that may be searched like a database. one can print the whole catalog or select search criterion to narrow the field. These programs will run on a P.C. , XT,and AT with a minimum of; 128K ram 1 double sided floppy disk Mono or Color Graphics Adaptor DOS version 2.10 or above The FX-80 parallel printer is supported and a math Co-processer version is avalable from the authors.
