The Chromospheric and Photospheric telescopes, were installed in 1957. The both of these telescopes (two tubes) were mounted on the same Parallax Unit, and therefore they have a common Remote Control and the Clock Mechanism.
The Chromospheric telescope. Refractor.
(A) Objective diameter: 6 cm.
The telescope - narrow spectral band interference - polarizing filter, allows to get the 1.7cm diameter image of the Sun (in the center of H alpha line), with the Chromospheric features such as: Prominences, Filaments and Eruptions.
The Photospheric telescope. Refractor.
(A) Objective diameter: 13 cm.
(B) Focal length: equivalent: 865 cm;
Telescope gives 7.8 cm diameter image of the Sun (in the White band) with the Photosphere features, such as: Granules, Sunspots and Solar flares;
Both of these telescopes are in working condition
