Tours are conducted in the Rocky Mountains throughout the week. It consists of looking through telescopes, learning how to find objects in the sky using binoculars, a talk about the cosmos and a Q & A session. Guests are free to stay after the show to continue looking at the stars as I take down my equipment.
