About Astromania 2" Narrowband Nebula Red Filter
The filter is an Ultra High Contrast type of filter that is very effective for small and fainter emission and planetary nebula and a variety of bright nebula, especially through larger scopes. Another nice feature of the filter is the very natural coloration yielded by this UHC type filter. Star images retain a much more natural color, in addition to pinpoint star images. High transmission at the 656.3nm Hydrogen Alpha emission line is a bonus for this design.
