Version:  39.22

Requires: MC68020/68881
          OS 3.0
          Harddrive (20 MB space)
          6 MB FastRAM
          MUI 3.8

Recommended: MC68040 or MC68060
             OS 3.1
             16 MB FastRAM
             CyberGfx 2.25+ (=40.113+) or 3.x

Additionally recommended:
* The tower.library by Christoph Feck.
* The rgfx.datatype by me.


IMPORTANT:

Digital Almanac 39.22 requires the unpacked data archive of "DAlmanac_Data.lha" 39.11 !!

The large star database in the extra archive is for registered users only !!

This exe-archive contains an extra installer script for installing the data archive.

For complete installation, follow these steps:
* Download both archives.
* Unpack the exe archive.
* Start the exe installer.
* Start the data installer.


A French catalog is available, but not a French documentation, because I don't speak
French :-). The french installer script is only partly in french !


INTRODUCTION:

Digital Almanac is one of the best programs for hobby astronomers (and professionals ?)
available for the Amiga !

It offers:
* Star database with ca. 500,000 stars up to 16m.
* Cross-index for SAO, PPM, HD, YBS und GC catalogs.
* About 40000 deep sky objects (Messier, NGC, IC, UGC, Abell, Zwicky and other misc objects).
* About 40000 minor planets and asteroids as well as the
  Comets Halley, Hyakutake and Hale-Bopp.
* Highly accurate calculation of Moon and planets with JPL's integration tables (DE404).
  (Accuracy partly <0.1'' over a period of some thousand years !!).
* Moons of Jupiter and Saturn.
* Textures for planets Venus to Pluto, Moon and Galilean Moons.
* Milky way structure.
* View the sky from any solar system object.
* Animation mode (also saving in IFF-ANIM format !!).
* Loading and saving of configuration files.
* Highly optimized algorithms for maximum speed, mostly written in assembler.
* Lots of configuration possibilities.
* Online and menu help with HELP-key and MUI's bubblehelp.
* Creation and export of ephemeris tables.
* CyberGfx High- and Truecolor mode support.
* Picture galery creation.
* User editable database of orbital elements.
* Recognizes CPU for maximum speed.

And of course lots of bug fixes made in the previous versions.

Included in the archive are two project files of a solar and a lunar eclipse ready to watch !

THIS PROGRAM IS SHAREWARE!

Following features are restricted for non registered users:

* Deep-sky catalog access limited to the Messier catalog.
* All saving functions are disabled.
* No hardcopy.
* No changing site to a different planet, only Earth enabled.
* No detailed course of eclipses.
* No picture galery.
* Plotting stars only to 6m.
* Plotting other objects only to 10m.
* No changing of pixelsize.
* No events in the calendar.
* Ephemeris export only to a window.
* The program will terminate after 20 min and all 5 min a requester will appear.

Changes since 39.18:
* Fixed wrong milky way position.
* Fixed bug in refraction.
* Improved time stringgadget in "Coordinates window".
  You may enter only HH or HH:MM.
* Added textures for Saturn, Uranus and Neptune, Pluto and the Galilean Moons.
  Improved textures for Venus, Earth, Mars and Jupiter.
* Dynamic allocation and buffering of textures.
* Removed tooltype NOTEXTURES.
* Moons of Jupiter and Saturn can now be drawn with a planetary grid.
* Azimuth output in export mode didn't recognize azimuth mode.
* Added keyboard support for MUI's register groups.
  I have forgotten this the whole time ;-)
* Added gadget for color remapping.
* Improved night palette.
* Fixed a minor bug in error message requesters during program's initialization.
  Better error diagnosis when startup failed.
* Improved ephemeris export.
  Export to window is possible.
  Automatic output filtering of unused datas.
* Corrected ephemeris of stars and deep-sky object when site was not Earth.
* Added pixelcheck gadget.
* Updated asteroid database. Contains 39659 entries.
* Improved look of the documentaton.
* Fixed a little bug in date conversion, which could have lead to a guru under certain
  circumstances.
* After a long time the bubble help in the main window works again.
* Added "Fast SinCos" functions. Increases speed up to 15%.
* DA crashed when there was not enough mem during anim initialization.
  This has been fixed.
* Fixed a bug in CGX support. Switching back from hi/truecolor to 8-bit screen caused
  some corrupt pixels.
* Added clipboard support (IFF-ILBM).
* Reduced memory usage when saving map as ILBM.
* Added option "Extinction".
* Updated star database.
