Product description

These 3.5 nm H-alpha Enforced-Narrowband Filters open up the extremely narrow 3,5nm H-alpha world. This enforced contrast results in even fainter stars, providing more signal of faintest nebulae detail. Manufacturing such ultra-narrow filter does require extreme coating homogeneity and very high Center-wavelength precision, which these filters are designed for.
