The Jacobus Kapteyn Telescope or JKT is a 1-metre optical telescope named for the Dutch astronomer Jacobus Kapteyn of the Isaac Newton Group of Telescopes at the Roque de los Muchachos Observatory on La Palma in the Canary Islands, Spain. Funded jointly by the Netherlands and the United Kingdom with planning throughout the 1970s, construction of the JKT was completed in 1983 with the first photographic plate taken in March 1984. It can be used with two different focal points and different instruments, although by 1998 this was refined to one CCD imaging instrument. The telescope weighs nearly 40 metric tons in total.〔(【引用サイトリンク】title=The 1.0-m Jacobus Kapteyn Telescope (JKT) )〕 Being superseded by more recent and larger telescopes, it was taken out of service as a common-user facility as of August 2003. Since 2014, the telescope is owned by the Instituto de Astrofísica de Canarias (IAC) and operated by the ''Southeastern Association for Research in Astronomy'' (SARA)〔 which is now working to enable the JKT as a remotely operated observatory, with the first new observations scheduled for October 2015. == See also == * List of largest optical telescopes in the 20th century 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「Jacobus Kapteyn Telescope」の詳細全文を読む スポンサード リンク
