论文摘要
我们描述了为俄罗斯科学院特殊天体物理观察员和莫斯科州立大学斯特恩伯格天文学学院的2.5 m望远镜开发的新型可调节滤器光度计的设计和操作原理。该仪器安装在扫描Fabry-Perot干涉仪上，在可调式滤波器模式下运行的光谱范围为460-800 nm，典型的光谱分辨率约为1.3 nm。它允许人们在具有不同激发条件的发射线中创建银河系和外层状星云的图像并执行气体电离状态的诊断。观测，数据校准和还原的主要步骤通过不同的发射线对象的示例说明：银河系HII区域，行星星云，具有延长细丝的活性星系，Starburst星系和Perseus Galaxy Galaxy群集。
We described the design and operation principles of a new tunable-filter photometer developed for the 1-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences and the 2.5-m telescope of the Sternberg Astronomical Institute of the Moscow State University. The instrument is mounted on the scanning Fabry-Perot interferometer operating in the tunable-filter mode in the spectral range of 460-800 nm with a typical spectral resolution of about 1.3 nm. It allows one to create images of galactic and extragalactic nebulae in the emission lines having different excitation conditions and to carry out diagnostics of the gas ionization state. The main steps of observations, data calibration, and reduction are illustrated by examples of different emission-line objects: galactic HII regions, planetary nebulae, active galaxies with extended filaments, starburst galaxies, and Perseus galaxy cluster.
