Clear Sky Chart
So as not to disappoint anyone, calling this an 'observatory' is a bit of a stretch. But we have some magnificent night skies, and terrific places to observe from. The clear sky chart to the right is available from the Canadian Meteorological Centre and customized to our location.
The chart and legend for interpreting it are available from http://www.cleardarksky.com/c/4CrnsObONkey.html?1
