Observing difficult, dim Deep Sky targets like Planetary Nebulae and certain supernovae remnants, such as the Veil Nebula in Cygnus from light poluted environments can be a very tricky business.
Optolong extra narrowband SII-CCD 6.5nm filter (Sulful II for CCD) is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths
The Astronomik CLS is a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.
The H-Alpha 7nm filter is the most popular narrowband filter allowing 7nm bandwidth of light centered on a wavelength of 656nm through, and reducing the transmission of certain wavelengths of light

This Astronomik OIII-CCD Filter is suitable for imaging of OIII nebulas from observation sites with light pollution and from dark sites as well. The contrast between an object glowing at 501nm and the background is increased enormous!
The Astronomik H-beta filter is a narrow band emission-line filter for CCD photography. The filter lets the H-beta light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive.
The Astronomik SII-CCD filter is a narrow-band-filter for CCD photography.The filter lets the light of the ionized sulfur (SII) pass, and blocks nearly the whole remainder of the visual spectrum as well as IR, in which the CCD is sensitive.
IDAS NB Filters are designed to enhance the contrast of emission nebula, yet accommodate the filter spectral shift* when used with modern fast optical systems.
The popular CLS clip in filter now available for full frame cameras such as the 5D and 6D. A very useful light pollution/deep sky filter for SLR imaging.
L-Quad Enhance Filter is a quad bandpass light pollution suppression filter for colour cameras. It effectively suppresses the transmission of light pollution wavelengths
