WDS Data

A new Washington Double Star data file is available (Jan 31, 2003). This update fixes a processing problem in the original version which caused a reversal of the Declination sign for many of the entries.

Note: In order to use this update, you must be accessing the "StarData" files from your hard drive and not from the CD-ROM.

Run the self-extracting exe file below and extract the contents into MegaStar's "StarData" folder. To confirm the proper path for your installation, click the "File | Select Directories" menu in MegaStar and look at the path specified for "Non-GSC Stellar Data".

RealSky Conversion Utility

If you frequently move around the sky with RealSky displayed, the need to swap CDROMs can become annoying. This can be avoided by putting the RealSky data onto your hard drive. To do this, you will need to use the LoadRS.exe program. Run this program by double-clicking the LoadRS.exe file in Windows Explorer, or by using the Run command in the Start menu. Click on “Help | Tutorial” in LoadRS for instructions.

To load the entire RealSky onto your hard drive will require about 11 GB of free disk space. However, you can load only a portion of the sky if you want. After placing the data on the hard drive, select the Read data from hard drive option in the RealSky Options dialog box. You must also enter the path on the hard drive where the data has been loaded. A “Browse” button is provided for navigating the hard drive folders. If only a portion of the RealSky has been loaded, you may want to also select the option Use CD-ROM if HD data is not found. MegaStar will then try to access the data from the CD-ROM drive if the data is not found on the hard drive.
