- StarAtlas v-0.8
- Written by Youhei Morita using THINK C 5.0.
-
- This program draws a map of a region of the sky. It also displays
- the positions of the Sun and planets. (Moon is not supported yet.)
-
- Version 0.8 is a beta release. It runs on System 6.0.7, 7.0, 7.0.1
- and 7.1. A 68020 machine or above is recommended. Send bug
- report to the author if you find any problem.
-
- To run this program, an accompanied data file "yale.star" should be
- placed in the same folder as StarAtlas. This file is the Yale Bright
- Star Catalog which contains 9096 stars up to magnitude 7.
-
- When you launch StarAtlas, it displays the map of the Sky after
- loading yale.star file.
-
- You may receive a message "Map is not found in Control Panel.
- City name will not be resolved." at this point. StarAtlas looks
- up a control panel file "Map" in your System Folder to resolve
- the default city name in your PRAM setting. If you want to
- get rid of this message, put "Map" in your System Folder (or
- Control Panel), or just ignore the message. StarAtlas runs with
- or without "Map".
-
- First screen you will get is the sky around Orion and the Winter
- Triangle. You can change the center coordinate by clicking any
- portion of the map. It also can be changed through the "R.A."
- and "Decl." menu. "Zoom" menu changes the scale of the map.
-
- If you are using color display, color of each star represents the
- spectrum type of the star. It may or may not reflect actual color
- of the star you see with your naked eyes.
-
- "View" menu changes the view of your StarAtlas display to
- StarAtlas, Planetarium or Solar System.
-
- You can change various options in "Preference..." dialog in the
- "Edit" menu.
-
- Display star names brighter than...
- Draws the names of star whose magnitude are brighter
- than the specified value. Choice of "Greek & Constellation"
- or proper name of stars.
-
- Display Sun and planets
- Draws the Sun and planets positions on the map.
-
- Display Atlas scale
- Draws the Right Ascension and Declination scale on the map.
-
- Display Equator and Ecliptic
- Draws the Equator and Ecliptic lines on the map.
-
- To change the Date and Time setting, use "Date & Time..." dialog
- in the "Edit" menu.
-
- StarAtlas uses the longitude, latitude and time zone stored in
- your Mac's PRAM as a default. If you have never set your city in
- the "Map" in your Control Panel, the Planetarium view may not
- reflect the correct view. Before you launch StarAtlas, use "Map"
- Control Panel and set your city and time zone.
-
- You can also tell StarAtlas about your longitude, latitude and time
- zone. Use "Location..." dialog in the "Edit" menu. This setting is
- effective only in the StarAtlas.
-
- "Recalculate" command in the "Edit" menu redraws the screen
- without changing the StarAtlas settings.
-
- Solar System view is expressed in terms of Sol-centered equatorial
- cartesian coordinate. The left side view contains the inner planets
- (Mercury to Mars) and the right side view contains the outer planets
- (Mars to Pluto). In x-y view, you are looking down the Solar System
- from the North Pole of the Atlas, and in x-z view you are looking
- from the Snake Charmer (R.A. = 18h, Decl = 0°).
-
- You can save the loading time of yale.star if you create yale.star.bin
- file by selecting "yale.star => yale.star.bin" in the "Convert" menu.
-
- StarAtlas is freeware (postcardware). If you like this program,
- send a postcard of your town to the author. Also send your
- suggestions for improvements in the next release. If you use this
- program for any practical purpose, and would like to support it, send
- what this program is worth to you to the following address. It will
- help the author to buy Macintosh programming books such as Inside
- Macintosh. US checks are gratefully accepted.
