You might have a point there Paul, THE SKY 6, or my copy at least isn't actually listing Antares as a double.(except it does list 2 spectral clasifications. It was only by zooming in on the map til it showed seaparation and then that separation measured in at 0.55". I am seriously beginning to wonder if the data files are corrupted though because it is doing a few other strange things lately. Nortons star atlas gives 2.6" and some web page I looked up gave a separation of 3"
cheers,
Doug
