Baader narrowban H-alpha filter 6.5 nm (1.25")

The Baader narrowband H-alpha low-end filter is the first choice for astrophotographers - if they want to get excellent images at H-alpha wavelengths optimized for the most contrasty CMOS but also on CCD. The filters have excellent light transmission in the H-alpha wavelength range, while at the other "unwanted" wavelengths they cut off the light completely. They guarantee excellent results when used with binoculars from f/10 to f/3.5.

The excellent glass material and machining of the filters promise excellent contrast and sharpness. The coatings are applied to the glass material using state-of-the-art tools that guarantee an ideal transmission range. Anti-reflective coatings contribute to excellent imaging and the surfaces are treated to make the glass material scratch-resistant.

Not for daytime observation!
