日本国立大学天文台建设在夏威夷的可见、红外大型望远镜(昴宿星团)迎来了第一熹微光。就是首次向已完成的望远镜导入天体光,进行各种调准、确认性能。这个阶段虽然还没有发挥出望远镜的实力,但可以确认出高性能。 在成像性能方面,在好的透明度下采用近红外(2μm波长)时可以得到0.3秒角(1秒等于1/3600度)的星像尺寸,可见光时(0.6μm) The observatory of Japan National University Observatory built in Hawaii, the infrared large telescope (Pleiades cluster) ushered in the first Xi shimmer. It is the first time to import celestial light into completed telescopes and make various adjustments to confirm the performance. Although this stage has not yet played the strength of the telescope, but you can confirm the high performance. In terms of imaging performance, star images with a 0.3 second angle (1 second equals 1/3600 degrees) at near infrared (2 μm wavelength) with good transparency can be obtained at visible light (0.6 μm)
