Evaluate sky conditions suitable for astronomical viewing.
Clear Sky Clock Widget is a simple and easy to use dashboard widget for evaluating sky conditions suitable for astronomical viewing. Simply install the widget, flip it over, and choose the location of interest. The data is retrieved (with permission) from Atilla Danko's Clear Sky Chart Web pages. Instructions on how to interpret the clock are located there (although a legend and re-sizing of the widget are now built-in). [Dashboard no longer exists in macOS 10.15 Catalina, so this widget will not work on macOS 10.15 or later.]
