This filter is optimal for a OneShotCamera (as in Color Camera), best if used on an astromodified camera or dedicated astrophotography camera.

This filter lets through light from emissions of H-alpha and OIII (Oxygen). So best look for nebulae, which are rich in light-emitting hydrogen and oxygen.
