Narrowband Sulphur S-II nebula filter by Baader-Planetarium for astrophotography with CMOS sensors for high contrast for telescopes from f/10 - f/3.5
2" mounted with filter thread on both sides
Low profile filter cell - height only 6 mm
Optimized for CMOS sensors (Color and MONO)
Reflex blocker coating against reflections in combination with correctors placed near the filter
Exact and narrow FWHM for optimal signal-to-noise ratio
Identical filter thicknesses for parfocality (not parfocal to older Baader filters!)
The front side is marked in the form of a black outer edge (front side indicator)
The edge of the filter is sealed, so no moisture can get in
Life-Coat - an even harder coating for a virtually unlimited lifetime
