An application for eclipse chasers, by an eclipse chaser.
Sciatrope is a Cocoa (macOS) application made by an eclipse chaser for eclipse chasers. It helps preparing for, and observe, any solar eclipse. It gives the eclipse circumstances, distance and direction to the central line. Observing location can be provided by the Mac, an external GPS, by location name, from a previously saved favorite location, or by latitude and longitude. Eclipse circumstances are displayed in tabular form, on a map, a compass, or in an image, with azimuthal or equatorial orientation, which can be flipped horizontally, vertically, or both. The map also displays the eclipse path, with the central line and the north and south limits of the central eclipse. The eclipse path is refined when you zoom in. For the experts or adventurous, eclipse elements can be modified, to take into account new updated elements, or experiment with the Besselian elements.
