Levenhuk Ra O-III 2'' filter is a narrow-passband filter with a barrel diameter of 2'' that transmits wavelengths of the visible spectrum within 150 Å (15 nm) range. This filter suppresses all light that lies outside its 4900–5010 Å (490–501 nm) passband and is perfect for observations of nebulae. Keep in mind, however, that this filter gives a green tint to observed objects.
This filter is highly effective under urban illumination conditions and may be used for urban stargazing and astrophotography, as it reduces light pollution and enhances the contrast of observed objects.
General use product. May be used by kids over 3 years old.
