The AllSky camera is extremely light sensitive, so on clear days the Sun either creates an over exposed column of white light, or the whole image may become overexposed. At night when the clouds are away, planets, stars, constellations, and the Milky Way can be seen (even the Northern Lights! when they are active).
Each AllSky image is oriented such that north is to the right, west is on the bottom, south is to the left and the eastern sky can be seen at the top. The dome seen on the left houses the Baker-Nunn telescope. Downtown Calgary is on the northeast horizon (behind the satellite dish). The top of the dome housing the 1.8 meter A.R. Cross telescope can be seen at the eastern edge of the image.
The darkest and most pristine skies can be seen opposite Calgary, towards the south and southwest. Even though a glow of light can be seen from the city at night, the RAO is still under dark skies, especially when the moon is below the horizon.
The University of Calgary thanks residents of Foothills County for their efforts to keep their exterior lights pointed downward. The University is also working with the City and the Alberta government to minimize sky glow from the Alpine Park and the Southwest Ring Road developments.
