Alberta's night sky spectacular
Alberta boasts two of the world's largest dark sky preserves. The Wood Buffalo and Jasper national parks offer photographers the chance to take some spectacular pictures of the northern lights and the night sky.
Astrophotographers Yuichi Takasaka and Ryan Bray talk about their work and share some of the images from their lenses.
