Extrasolar: Stars:
Castor - a sextuple star system

Summary:The six stars (3 binary pairs) of Castor in their orbits.
Description:In standard Celestia, Castor is only represented as a single star. In fact, Castor is a sextuple star system comprised of three different binary stars.
The add-on provides the six stars (3 binary pairs of Castor in their orbits - as far as they are known.) It also provides a script which will take the novice user of Celestia on a short guided tour of the Castor system.

To install this add-on, please view the InstallREADME.txt file which is included in this package.

It will work with 1.4.x versions of Celestia, however it is highly recommended that you install Celestia v1.5.1 or later before installing this add-on.

I suggest you to fix the magnitudes.
Now all of the six stars have the same magnitude as the single one as seen from Earth. This results in a "total" Castor 6 times brighter. I have calculated the right ones, and now it works better! If you want the .STC please contact me at my author e-mail! ^^

This is a nice add-on. I am actually surprised I never got it earlier!

I love the addon. I have just a few tips:
~ You don't need to duplicate all of Castor's names in the definition. By giving the "Castor " barycenter Castor's HIP number, it automatically inherits all of Castor's names.
~ Castor AB probably shouldn't have the already-used HIP and SAO numbers.
~ The disabled barycenter is unnecessary. By overriding Castor's HIP number, you also delete the old Castor.

Very interesting. I must say though, the beggining of the script could have given someone a seizure, so you may want to look into that.
