Astronomical information about the universe

We are a group of amateur astronomers working together to improve astronomical knowledge and observational skills. We make ourselves and our instruments available to promote public interest in astronomy. Cosmos members are a varied group of colleagues who share a curiosity about the sky. Some members are scientists or engineers, while others are artists or craftspeople, building contractors or college students. Ability levels span the range from novice to expert.


Our company was founded in 1976, with the goal to produce and market innovative observational astronomy aids and educational materials for amateur astronomers and students of all levels.
