The planisphere oval represents a 'window' of the night sky for most Canadians*. For each day of the year, the position of the stars and constellations is shown for Midnight, not taking into consideration Daylight Savings Time, which varies from province to province. Therefore, you may notice slight adjustments in the exact position of the stars in Canadian night skies.

The constellations close to the Southern Horizon will be in front of you when you look southward. Similarly, the stars close to the Northern Horizon will be in front of you when you look northward. The same rule applies for constellations close to the Eastern and Western Horizons. The stars in the middle of the oval will be directly over your head.

*Canadians living between 45° and 55° latitude.
