Unfortunately for those of us who live in Leeds the eclipse is not total, but telling Copernicus to draw the map from a suitable south of England location results in a total eclipse being shown. The software is accurate enough to tell whether an eclipse is annular, partial, total or a near miss when viewed from any point on the globe. The same zoom window can also be used to study occulations of stars by the moon or transits of the sun by mercury or venus. If you look closely you will see that the name of the star that the mouse pointer is pointing to is displayed in the zoom window's title bar. It explains all aspects of the software, contains a tutorial section, and includes more explanations of the astronomical terms used in Copernicus.
Help is continuously available in the button bar's title bar.
Copernicus contains several thousand more stars than earlier versions and a larger range of star maps including better views of your local horizon and the ability to draw any part of the sky given the appropriate coordinates by the user. Copernicus will not run on an ordinary PC - it needs an Acorn RISC OS computer.
