In recent years, most results of CaII studies of the solar chromosphere in H and K lines have been based on observations with narrow passband filters. The Baikal Observatory’s full-disk chromospheric telescope for the K CaII line with a birefringen

A chromospheric telescope is an important instrument for synoptic observations and solar research. After several decades of observations with the chromospheric telescope at Baikal Astrophysical Observatory, a need arose to improve the characteristics

Nowadays, Coronado, Lunt, Solar Spectrum, Daystar and Solarscope companies advance available narrowband solar filters. Being installed in small telescopes they allow amateurs not only to admire grand phenomena in the solar atmosphere but also to be i

A 24-element wide-field Solc birefringent filter (WFSBF) has been produced and tested for the first time. WFSBF is a second unit to the 3-unit BF designed for imaging solar magnetic fields in the FeI 6173 A spectral line. WFSBF passband full width at

A wide-field birefringent filter for the barium II line at 455.4nm is developed in Irkutsk. The Barium line is excellent for Doppler-shift measurements because of low thermal line-broadening and steep flanks of the line profile. The filter width is 0
