Anyone interested could visit this site: http://home.earthlink.net/~stanleymm/CCD_topics.html

Hi Doug,
I'm not sure what that overseas made astronomy software is doing to you, but according to the Australian made STAR Atlas PRO software, Antares is seperated by 2.9" from it's hot companion star which is also strong radio source.
STAR Atlas PRO says it is a Magnitude 5.4 star with a B2.5V Spectral Type at a Position Angle of 275 degrees with an Angular Separation of 2.9 arc seconds and catalogued as CDM16294-2626B. Antares has a parallax measurement of 5.40 milli-arcseconds which equates to a distance of 604 Light Years.
Gee, you guys really need some better astronomy software
