[Owl and the Moon]

[Owl Observatory]
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 Wednesday, 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 being erected.

The original telescope, a homemade 10-inch Newtonian Reflector, was finally added during the Spring of 1998, which put the observatory in working order. The observatory was dedicated on August 22, 1998.

A campaign to upgrade the observatory began in the spring of 2000. The members of the Kalamazoo Astronomical Society (KAS) took advantage of the partial solar eclipse that occurred on Christmas Day of that year and purchased 1000 pair of eclipse shades. Through sales of the eclipse shades and many generous donations, the KAS purchased a new instrument a year after the campaign began and installed it in June 2001.

The observatory is located on the grounds of the Kalamazoo Nature Center, which is recognized as one of the nation's best nature centers. Since 1960, the Nature Center has been inspiring people to care about the environment by providing experiences that lead them to understand their connection to the natural world. It is located on 1000 acres of rolling hills in Southwest Michigan with a variety of habitats, including mature beech-maple forests, wetlands, and prairies. The KAS has been holding public sessions at the Nature Center for nearly three decades and the observatory increases our long partnership. The Nature Center offers reasonably dark skies, yet is located only six miles north of downtown Kalamazoo.

Owl Observatory is a 12' x 12' building with a roll-off roof which exposes the inside to the night sky. Roll-off roof observatories have several advantages over domed observatories. Some of which include the following:
  • They are simpler and less costly to build than a dome.
  • Does not require complex motors and electronics to move as the telescope follows the sky.
  • Reaches thermal equilibrium faster than a dome, and does not create a chimney effect as hot air rises out the open slit of the dome.
  • Permits an unobstructed view of the sky for naked eye observations and wide field piggyback astrophotography.
  • A roll-off roof building can be disguised as a shed to camouflage the expensive equipment inside.
The building's walls help protect observers from wind and extraneous light, but may be lowered when necessary. The heart of the observatory is a Meade 12" LX200 Schmidt-Cassegrain Telescope (SCT). Such telescopes have become very popular among amateur astronomers and small observatories since they are compact and offer many sophisticated features. The LX200 telescopes are computer controlled, permitting quick, automatic access to thousands of stars, star clusters, nebulae, and galaxies.

The telescope is equipped with a complement of eyepieces and accessories, including astrophotography aids and a solar filter, to support a wide range of observing programs.

To facilitate serious observing, the telescope is supported rigidly on a steel pier, which, in turn, is bolted to concrete pads sunk deep into the ground and physically isolated from the rest of the building to avoid vibration and effects of wind. The telescope is equatorially mounted to provide accurate tracking of stars for astrophotography.

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 be making use of the observatory for their observing programs. The KAS owes a sincere expression of gratitude to those members and many donors who stepped forward with cash donations and in-kind support to make this facility a reality.
