In the nebula filters category you will find both broadband and line filters. The latter only selectively allow the light of a certain spectral line through. OIII and H alpha filters are especially popular. Many deep sky objects will only reveal their full glory when observing using these filters!

As the name suggests, wideband and narrowband filters pass a wider range and narrower of the spectrum. They are used primarily to suppress light pollution.
