Carry your favourite Clear Sky Charts (CSC) in your pocket Amateur astronomers in North America monitor local sky conditions using the CSC web sites which provide a very detailed 48 hour color coded observing forecast chart for cloud cover, transparency, seeing and other factors. This app contains a database of more than 5200 forecast locations in Canada, the USA and Mexico and can check for new updates. A portion of every copy purchased will go to Attilla Danko to help support the ongoing operation of the Clear Sky Charts site.
