MacAstro

Description

MacAstro is a program for astronomy lovers to calculate the appearance of the sky at any time and any point on earth. It displays the position of the 8 major planets, the Sun, the Moon, and 2500 brightest astronomical objects (stars and Messier's objects).

These are the main features of the program :

• Full Macintosh interface.
• Background calculations.
• Displays in color the position of the objects of the Solar System (8 planets + Sun + Moon) and displays the position of the 2500 brightest stars in the sky, according to the date and place of the observation.
• Displays the constellations.
• Displays the ephemeris of any of the 2510 objects:
  • rising/setting/culmination,
  • right ascension/declination,
  • azimuth/altitude,
  • visual magnitude and diameter,
  and allows to save it to a text file for the planets, the Sun and the Moon.
• Displays and exports a picture of the phase of the Moon.
• Displays and exports a picture of Jupiter and Saturn's satellites position.
• Displays the sidereal time.
• "Planetarium" mode : an animation refreshes regularly the appearance of the sky (can turn in background under MultiFinder).
• Editable list of most commonly used places of observation, and possibility to use the location coordinates stored in the PRAM.

Requirements

Macintosh Plus, Classic, or larger and a system 6.0 or later.

Notes

I found it necessary to increase the amount of RAM used by the program.
