The Omegon light pollution filter is a type of broadband filter. Its effectiveness makes it universally applicable. The wide passband allows for better viewing of star clusters, galaxies, nebulae, and comets. However, it also filters annoying artificial light such as street lighting.
Omegon UHC and Omegon OIII filters are limited in application to a few objects. Therefore, the Omegon light pollution filter is most useful for increasing the contrast of faint objects, without filtering out the spectrum of potential observation targets.
The Omegon Light Pollution Filter is not only useful in places with light pollution; contrast is also increased at dark sky sites.
The advantages in a nutshell:
a first filter for those on a tight budget
well suited for smaller telescopes
can also be used for astrophotography
stars are not as intensely colored as with a narrow band filter
