Rothney Astrophysical Observatory
The sky holds many surprises when you can see the whole picture at once! Because the camera is extremely light sensitive, the Sun creates a white vertical line. On very bright sunny days, the whole image may be over exposed. Images taken from sunset to sunrise are best. Planets, constellations, and the Milky Way can be seen on clear nights!
What does this image show? Well, it's essentially the whole sky! North is at the right and South is at the left. West is at the bottom and East is at the top. The point on the sky straight over the RAO is at the center.
The dome to the left houses the 0.5 wide field Baker-Ninn Cross Telescope. Downtown Calgary is on the horizon behind the satellite dish to the NE. The dome at the top houses the big 1.8 m A.R. Cross Telescope. The darkest and most pristine skies viewable from the RAO are away from the city, toward the south and SW. Click the image for a large view.
Although sky glow from Calgary can be seen at night, the RAO is still under very dark skies when the Moon is below the horizon. The University of Calgary thanks residents of the MD Foothills for their efforts to keep their lights pointed downward. The University is also working with the City and the Province of Alberta to minimize sky glow from the Providence and the Southwest Ring Road developments.
