Sherzer Observatory is an astronomical observatory located on the campus of Eastern Michigan University. The observatory was established in 1878, in Ypsilanti, Michigan. The new observatory opened in September 1991 with a apochromatic refractor telescope and German equatorial mount centered under a 6-meter dome. ==History== Sherzer Observatory was established in 1878 with a gift from the citizens of Ypsilanti. The Observatory housed a , $600 Alvan Clark refractor. The original observatory was located on Pierce Hall was hit by a tornado and destroyed in 1893. It was then relocated to the roof of the new Natural Science Building in 1903. The building and observatory was later named after William Sherzer, a science professor at the school who conceived the design for the new building after seeing similar facilities on a visit to Germany. In 1928, a refractor telescope manufactured by telescope maker and amateur astronomer John Mellish was installed on a German equatorial mount built by physics professor Edwin Strong. The University Archives still has data produced by students using this telescope and the brass Negus transit telescope which shared the observatory with the refractor. In the 1970s and 1980s, members of the EMU student astronomy club made numerous updates and restorations to keep the aging observatory running. Then, in 1989, Sherzer Hall was gutted by fire. Almost half of the building was destroyed including the original observatory. Fortunately, the University decided to rebuild. The new observatory opened in September 1991 with a apochromatic refractor telescope and German equatorial mount centered under a 6-meter dome. A classroom/computer lab was finished in 1997, and additional to telescopes, CCD cameras, and other equipment added to the inventory for student use. A secondary observatory with an automated SCT for CCD imaging was added to the rooftop level, becoming operational in 2008. 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「Sherzer Observatory」の詳細全文を読む スポンサード リンク
