About the Observatory

In 2000, the Observatory was officially named in honor of Karl G. Henize because of his accomplishments as an astronomer and for his dedication to fulfilling his dream of reaching space. His name on the observatory will serve as an inspiration to the youth of today and tomorrow. Dr. Loren W. Acton, Astronomer and Henize's former crewmate dedicated the building in his honor.

The main telescope is a Meade 14" Schmidt-Cassegrain telescope (SCT) on an Astrophysics 1200GTO mount. This allows Harper faculty to do research grade work in the Henize Observatory.
