McMillin Observatory

The observatory was equipped with photographic cameras, a filar micrometer, and a custom Brashear spectroscope.

[3] The observatory was equipped with a 12.5 inch aperture refractor, the largest telescope in Ohio, USA on its debut in 1896.

[8] The refractor was reportedly given to Kaubisch Memorial Library of Fostoria in 1975, however it was not moved out due to its size and was put in storage when the University had the building razed in 1976.

[5] Then the telescope was eventually owned by Heidelberg University of Ohio, while it remains at Ballreich.

[5] The overall observatory was funded by the donations of the benefactor Emerson McMillion, who also gave five year endowment for a Fellowship in Astronomy, and he also funded an expedition to Hawaii to observe the 1910 apparition of Halley's Comet.
