Nebular Filters

Nebular filters pass selected portions of the visual spectrum and serve to increase the contrast and detail visible in emission nebulae. The most unversally useful filter of this type is known as a narrowband or ultra high contrast (UHC) filter. These filters are ideal for star forming regions, such as the Orion or Lagoon Nebula. Oxygen-III ranks as the second most useful of these filter types and is best applied to supernovae remnant that are rich in oxygen.
