Also recognized as the Horsehead Nebula filter, the Lumicon 1.25-inch Hydrogen-Beta Filter selectively isolates the hydrogen-beta line of the spectrum (486nm) within a narrow pass-band of just 9nm, ensuring maximum contrast. This allows for the observation of extremely faint nebulous entities such as the Horsehead, Cocoon, and California Nebulae.
