 Instructions and links for installing CNEBULAX in your hard drive



1.   Download the new installation ZIP file. It is around 30 Mb, so be patient if your internet connection is slow.

2.   Create a temporary folder (whatever you want, for instance c:\temp) and uncompress the ZIP file there to have access to the setup files. The setup is now in English and compiled with MS Visual Studio Windows Installer in MSI format. It is a completely new setup system. There is no need of external files anymore.

3.   Run the SETUP.EXE file and install the program following the instructions. Select as a folder for installing the program a short name, for instance C:\INDEX or D:\INDEX. The folder you decided as program root folder will be referred further as the [RootCNebulaXfolder] (complements webpage)

4.   a) Go to the folder you have selected for installing the program with the windows explorer.

      b) Create a shortcut there to launch CNebulaX

      c) Move it to the place you want in your startup menu, or desktop.

      Be sure that that the shortcut includes in the "start in" entry (shortcut properties), the folder that you have previously chosen for installing the program (C:\INDEX, D:\INDEX, or whatever).


      6.1. Update the EXE file with the latest compiled EXE file, which fixes bugs, expand the features, and make use of new databases (in the case there is a new one). Just overwrite the old EXE with the new one.

      6.2. Expand the basic installation adding more databases. The basic setup files include 2.5 million stars and 32,000 DS objects, and you must install supplementary databases to get CNebulaX gifted with all its power: 25 million stars and 1.25 million DSOs at the moment, plus 330,000 asteroids and comets. Everything in my web is free.

6.   The temporary folder where you decompressed the ZIP file is no necessary anymore: you can remove it for freeing HD space.

The first time you run CNEBULAX...


6.   The first run of CNebulaX will force the program to configure the folder locations (also available from the FILES button within the SETUP/CONFIGURATION frame) to create an INI file. The folders to specify are:

      (a) Root CNebulaX folder  (required) where CNebulaX.exe is located (default location)

      (b) Constellations/stars file (required). Default location is the same as CNebulaX.exe

      (c) NGC/IC project files (optional - do not mind it if you do not have these files already)

·         If you have downloaded the NGC/IC project for offline browsing preserving the site structure, you can specify the location of the DSS folder in your hard drive. If you do so, each time you click the map on an NGC or IC object, the viewer will display the picture (naturally the picture should be stored in the hard drive: not all NGC/IC objects are currently available).

·         If you do not have downloaded the NGC/IC project, the viewer will display the zoomed area surrounding the object instead (magnification can be changed), or a finder map. The NGC/IC project is thus not required to run the program, but it is a nice add-on.

      (d)  Standard image database folder (optional - do not mind it if you do not have these files). This feature is not provided, since my image collection (150,000 objects) comes from several sources under copyright restrictions. You can link images to the program to display them as far as you have kept certain rules for naming the files and subfolders. If you bought an image CD from someone else (as I did), or you create your own collection of sky pictures (as I also did), CNebulaX is prepared to display them as you click on the maps.


(e)  User database folder (optional - do not mind it if you do not have these files). A complementary folder for storing smaller image collections from mixed sources (the file names should also follow certain rules).

7.   Once configured click on the [PROCEED] to end the program, which will create the INI file. Only (a) and (b) are essential to run the program. Naturally, if (c), (d) or (e) are not available or properly configured, some warning messages will be displayed, although the program will start without any problem in spite of the messages. Thus, when the program ended (this is the normal way to write the INI file), just restart it to load the new INI file.

8.   That's all! Just Once you have restarted the program to apply the specifications in the INI file, configure the colors and the screen at your will, set the latitude, longitude and time offset, and enjoy it.

9.   Read the documentation (highly recommended) if you want to introduce yourself fast in the main CNebulaX features and knowing the shortcuts.


...   Again, DO NOT FORGET expanding the basic installation of CNEBULAX adding more databases, exes updates and documentation...
