Holcomb Observatory and Planetarium is a part of Butler University in Indianapolis, Indiana. A small observatory was built on the Butler campus on the east side of Indianapolis. The campus moved to the north side of Indianapolis in 1928 and the old observatory was torn down. The telescope was reconditioned in the 1930s and remounted on the new campus, but sat unused until 1945. In 1953, benefactor James Irving Holcomb and his wife gave $325,000 for the construction of an observatory. In October 1954, a reflecting telescope was installed by J. W. Fecker, Inc. The observatory was built on a hill on the north end of the Butler University campus. Planetarium equipment includes a Spitz A3P projector installed in 1981. The telescope was refurbished over 7 years beginning in 1995 by AB Engineering of Fort Wayne, Indiana at a cost of approximately $100,000. ==See also== *List of observatories 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Holcomb Observatory and Planetarium」の詳細全文を読む スポンサード リンク
