摘要
太阳精细结构望远镜能对太阳Hα色球和光球的同一区域进行同时性的高空间分辨观测。物镜通光口径Φ260mm,色球滤光器工作波段中心波长6562.8,透射带半宽0.24和0.46,谱线位移范围6562.8±1.5,色球照相太阳像直径为Φ85mm和Φ130mm两种;光球照相波段为5500,太阳像直径为Φ300mm. 太阳精细结构望远镜的第一台安装在云南天文台,经三年左右的试观测,已取得一批预期质量的观测资料.1989年3月通过中科院技术鉴定.
The solar fine structure telescope is used to make simultaneous high space resolution observations in the same region for solar chromosphere and photosphere. The clear aperture of the objectives is 260mm. The central wavelength of the working wavelength range of the birefringent filter is 6562.8 and it is tunable over the range of 6562.8±1.5. FWHI of its passband is 0.24 or 0.46. The diameters of the solar image used for the chromosphere photographic observation are 85mm and 130mm. The wavelength and the solar image diameter of photosphere photographic observations are 5500 and 300mm respectively. See Photo [2-6]. It was appraised by the Academia Sinica in March, 1989. The first telescope of this kind has been installed in Yunnan Observatory. A set of data showing promising results as expected have been obtained through the observations in the past three years.
