Olaf Harken

Founder of the Harken Observatory - Olaf got his interest in astronomy while he served as an officer on a destroyer in the Pacific. Standing watch in the middle of the night, the dark sky was brazened with star light. He wanted to know more, and years later after a successful business, he joined others to form the Pewaukee Astronomy Club. It had a unique position in that while they were constructing the new library they included the platform for an observatory to house a 12 inch reflector telescope. It may be the only observatory on top of a public library. If there in an interest in learning more about the sky, there are billions and billions to choose from including planets, black holes, nebulas, asteroids, and many kinds of stars. Olaf is also one of the founders of Harken Inc.  Harken, Inc. is a leading manufacturer and distributor of innovative sailboat hardware and accessories. Headquartered in Pewaukee, Wisconsin, Harken manufactures in the USA and Italy. Its network includes distribution in 48 countries

Mike Paquette

Club President - I have always been in awe of the heavens beyond our sky.  I joined the club in 2006 to learn more about the infinite wonders of this universe we are part of, as well as to share that experience with others who share a similar interest.
