Owl Observatory User s Manual Owl Observatory Overview Owl Observatory is an astronomical observatory dedicated to the public education in the science of astronomy and to viewing the heavens The name and design comes from a three part article written by Jim Krick of Great Falls Montana and featured in Astronomy magazine April June 1992 Ground was broken on October 16 1996 and construction of the observatory began shortly thereafter The only work completed in 1996 was digging out the foundation and the pit for the telescope mount After the winter months the concrete was poured and shortly after the building was erected The original telescope a homemade 10 Newtonian Reflector was finally added during the spring of 1998 which put the observatory into working order The observatory was dedicated on August 22 1998 A campaign to upgrade the observatory began in the spring of 2000 when the members of the Kalamazoo Astronomical Society KAS purchased 1000 pair of eclipse shades to sell for the partial solar eclipse on Christmas Day Through sales of the eclipse shades and many generous donations the KAS purchased a new instrument one year after the campaign began and installed it on June 7 2001 Public observing sessions are held at the observatory twice a month from April to October School and other similar groups will also have access to the facility At other times KAS members will make use of the observatory for their ob
