Broad-band filtersThe broad-band glass filters made in SAO RAS are used for the observation in the Johnson-Cousins (UBVRI) photometric system in the direct images mode.
The SDSS (ugriz) glass filters with anti-reflective coating made by Asahi Spectra USA Inc. are also available for direct imaging observations.
intermediate-band filtersThe set of passband filters with band width 70-200 A is available for observations in the Н-alpha, [SII], [OIII] emission line and in the continuum. The majority of the filters were made by Asahi Spectra USA Inc., the FN674 filter was made by NIIPP (Moscow).
N.N. Kisilev (MAO, Kiev) kindly provide the set of intermediate-band filters for observations of the emission bands in comets.
The narrow band filters for observation with scanning FPIThe sets of narrow-band (FWHM=12-25 A) filters are available for observations of galaxies in the [OIII], H-alpha, [NII], [SII] emission limes. You can use this IDL-program to choose the optimal filters for desired systemic velocities.
