2009年1月,大熊座太阳天文台(BBSO)的新太阳望远镜(NST)进行了第一次光观测。NST有一个1.7米的主要与1.6米的净孔径。首次观测结果在TiO和Ha的显示和讨论。NST主镜是迄今为止部署的最非球面的望远镜反射镜。NST还处于调试阶段,这一阶段的计划将被草拟。在建立和实施NST方面吸取的经验教训与ATST和EST望远镜密切相关,将进行讨论。NST有一个离轴的格里高利配置,包括一个抛物线的主要。热停止,椭圆二级和对角帽。主镜的焦比为f/2.4。望远镜下方的Coude实验室的工作波长范围为0.4 - 1.7 μ m,而包括远红外在内的所有波长在Nasmyth聚焦在圆顶地板上。(C)2010 WILEY-VCH Verlag GmbH & Co.

In January 2009, first light observations with the NST (New Solar Telescope) in Big Bear Solar Observatory (BBSO) were made. NST has a 1.7 m primary with a 1.6 m clear aperture. First observational results in TiO and Ha are shown and discussed. The NST primary mirror is the most aspheric telescope mirror deployed to date. The NST is early in its commissioning, and the plans for this phase will be sketched. Lessons learned in building and implementing the NST are germane or the ATST and EST telescopes and will be discussed. The NST has an off-axis Gregorian configuration consisting of a parabolic primary. heat-stop, elliptical secondary and diagonal Hats. The focal ratio of the primary mirror is f/2.4. The working wavelength range covers from 0.4 to 1.7 mu m in the Coude Lab beneath the telescope and all wavelengths including the far infrared at the Nasmyth focus on the dome floor.
