This program enables you to draw sky charts, making use of the data
in 16 catalogs of stars and nebulae.
The purpose of this program is to prepare different sky maps for a particular
I originally developed this program for my personal use, because I like to adapt my tools to my needs. In my opinion the functionality of Sky Charts might be of interest to amateur astronomers or students. Therefore I decided to distribute it as freeware. I feel that you should rather invest your money in buying a good eyepiece than to waste it on software!
Terms and conditions
"Sky charts" is a freeware. You can freely install and use an
unlimited number of copies for your personal usage or redistribute it on
any support under the restriction that you must not modify it and that
you have to include all the documentation files.
For the conditions and citations of the single catalogs, please refer
to the original descriptions in the files ".TXT" in the subdirectory
Sky Charts uses catalog extracts provided by these two institutions:
I also would like to mention the US Naval Observatory who kindly supplies the USNO-SA1.0 CD-ROM, the Central Bureau for Astronomical Telegrams for the elements of comets and asteroids and their permission to distribute these files, and Lowell Observatory for the asteroids elements.
The Saguaro Astronomy Club distribute is Database Version 7.1
Michael. G. Christensen produce the FITS table with Uranometria 2000
This program is entirely written in DELPHI 4.
Calculations of the ephemerides of planets between 1900 and 2100 are based on " Ephemerides of planets between 1900 and 2100 Chapront-Francou, Bureau des Longitudes 1996 ". The program serie96.f was rewritten in Pascal and include in a DLL.
Planets calculation between -3000 and +3000 are based on plan404 by Steve Moshier, a DLL interface this C program.
Calculations of the ephemerides of the Moon are based on " Lunar Solution ELP 2000-82B Chapront-Touze, Bureau des Longitudes 1988". The program elp82b.f was rewritten in Pascal and include in a DLL.
Planets satellites calculation between 1997 and 2020 use posxy by J.-E. Arlot, Ch. Ruatti, D.T. Vu et W.Thuillot, Bureau des Longitudes. The program diffpos.f was rewritten in Pascal and include in a DLL.
Many calculations are based on the essential "Astronomical Algorithms by Jean Meeus".
RealSky® CD support use a library developed by Bill Gray of Project Pluto.
Some graphic files format use the library " NviewLib.dll " by K. Nishita.
Some graphic components use the Delphi library RXLIB.
Support for GZIP compression format use ZLIB by Jean-Loup Gailly and Mark Adler.
Installation files have been produced using the freeware version of "Install Maker" by ClickTeam.
I will to thank specially all the people who translate the program in
Many thanks to Luca Crivelli and Greg Roberts for their help with the development of the program.
