H-Beta Filter 2"
This high performance CCD filter transmits only the Hydogen Beta emission line, and therefore is useful for greatly increasing the contrast of objects that glow in the corresponding region of the spectrum, for example the Horsehead, Cocoon and California nebulae.
Recommended for capturing H-beta emitting objects using CCD photography under dark skies
