Optolong OIII Filter 6,5nm 2" (50.8mm)
US$ 198.66Extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).
Optolong SII Filter 6.5nm 2" (50.8mm)
US$ 198.66Extra 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 of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).
Optolong H-Alpha 7nm 2" (50.8mm) v.2
US$ 202.19The H-ALPHA 7nm filter is the most popular narrow-band filter that allows a 7nm bandwidth centered on a 656nm wavelength.
Optolong H-Alpha 7nm 1.25" (31.8mm) v.2
US$ 136.85Bester H-alpha-Linienfilter für die Astrofotografie von Emissionsnebeln mit höchstem Kontrast und der Wiedergabe zartester Nebeldetails.
♦ schmalbandiger (<=7 nm) Linienfilter für wichtige Nebellinie
♦ bevorzugt für CDD-Kameras mit Full-Frame-Transfer-Technik
♦ 2 mm dick und somit homofokal mit vielen anderen Filtern von Optolong
♦ Interferenzfilter
♦ feinoptisch poliert
♦ mehrschichtig hartvergütet - reflexfrei und weitgehend kratzfestOptolong SII Filter 6.5nm 1.25" (31.8mm)
US$ 149.21Extra 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 of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

US$ 131.56Extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).
- The L-Pro CCD filter improves the contrast of deep-sky objects and reduces the sky background.
Optolong L-eXtreme Filter 2" (50.8mm)
US$ 264.00The advantage of the L-eXtreme filter is that there is no transmission between the H-beta and OIII lines, as there is no nebula emission lines there. In this case, it isn't letting light pollution come through so that maximize nebulas signal and make the sky background darker while imaging. The L-eXtreme filter should better isolate the emission lines only and better protect from light pollution.
