Abstract

There are presented first testing data and a design of a special Solc birefringent chain narrow-bandpass filter that allows an astronomical observation of the Sun in wide number of interesting spectral lines (Hα, CaIIK, Hβ, Hγ, D₁, D₃, etc.). It is described an idea of tuning of sub-filters that the filter is compound of. A special aberrationless off-axis Maksutov telescope meeting demands for constant solar image scale in wavelength from 380 nm to 760 nm is also presented. This telescope equipped with the proposed filter is designed as a unity providing a top quality imaging.
