Narrowband H-Alpha 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
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
Low profile filter cell - height only 6 mm
