iCSC: Clear Sky Chart Viewer

iCSC is an astronomy weather app for iOS that allows observers to easily view Clear Sky Charts on their device. The Clear Sky Chart, invented and maintained by Attilla Danko, shows at a glance when, in the next 48 hours, one might expect clear and dark skies for a specific observing site.
