Creighton University Observatory was located on the Creighton University campus in Omaha, Nebraska, United States. It was the first observatory in Omaha, and the second in Nebraska. It was used primarily for the instruction of students, though the directors did do some research in the observatory. The observatory was demolished in late April of 2022 to allow for the construction of a new Jesuit residence hall.

As part of his endowment to found Creighton University, John A. Creighton donated the money for a telescope made by J.H. Steward & Co. of London.

Telescope statistics

• Aperture – 5 inches
• Focal length – 84 inches
• Mount – equatorial, on a brass column on an oak tripod with three large casters
• Mounting gear – driving clock, graduated circles, clamps and fine adjustment screws on both axes
• Eyepieces – 7 total (1 terrestrial, 1 diagonal, 5 astronomical)
• Initial storage – in the chemistry laboratory, rolled out as needed
• Cost – £125 (approximately US$625)
• Usage intent – popular and educational use

Observatory built

Father Joseph F. Rigge, S.J. arrived at Creighton in August 1885. Assuming responsibility for the telescope, he noted that the constant movement of rolling the telescope in and out of its storage space did not allow for accurate usage and was even damaging the telescope. He suggested a small shed with a removable roof. Father Dowling, the university president, was able to secure $1200 from Mr. Creighton for building a proper observatory.

Observatory demolition

As a result of the construction of a new Jesuit residence alongside 24th Street, the observatory was demolished.[1] Portions of the observatory are being repurposed for a memorial.
