  • Enforced contrast results in imaging the faintest stars and nebulae with incredible detail

Product Details

  • The Baader Ultra Narrowband H-Alpha Filter opens up the narrow H-alpha world for your night sky imaging. The enforced contrast provides more signal of even the faintest nebula detail. Unfortunately, you're going to want to re-take some of your favorite astro-images with these elite filters!

    These Ultra Narrowband Filters are manufactured with a sophisticated process that requires extreme coating homogeneity and very high Center Wavelength Precision. It should be noted that in general, the H-alpha ultra narrowband filter is NOT suitable for solar observation. The half-bandwidth of 3.5nm = 35 angstroms, which is much wider than needed for high quality solar observation (sub-angstrom).
