Astronomik OIII 6 nm CCD Filter - 27 mm Round



  • Made specifically for astrophotography, this Astronomik OIII 6 nm CCD Filter is round and measures 27 mm in diameter
  • Close to full transmission in the OIII line
  • FWHM bandwidth of approximately 6 nm
  • The perfect filter for imaging supernova residue and planetary nebulae
  • Multi-layer coating technique provides protection against the damaging effects of scratching, aging, and high humidity
  • Diffraction limited, this filter will not lessen the optical performance of your telescope
  • Made in Germany, a country with a reputation for producing high quality optics
  • Best suited for instruments with 6" or larger apertures




More About Astronomik OIII 6 nm CCD Filters



OIII CCD filters are ideal for imaging OIII nebulae from dark as well as heavily light polluted viewing locations. This filter offers complete obstruction of unwanted light sources such as artificial light pollution, natural skyglow, and moonlight. Light from high and low pressure sodium and mercury lights, common light pollution culprits, as well as all lines of natural airglow are fully blocked. It highlights the tremendous contrast between objects glowing at 501 nm and the sky background. Using an OIII filter will broaden your imaging potential, as you'll gain ability to image all greenish and blueish objects.



A typical 96% transmission combined with a 6 nm narrow bandwidth provides a remarkable contrast gain since unwanted light from other wavelengths is fully blocked from UV up to IR. When compared to the 12 nm filter, the 6 nm OIII enables a higher contrast improvement due to its smaller FWHM (full width at half maximum). The result is an exceptionally dark background.



A fitting choice for imaging faint objects in areas of the Milky Way that are densely packed with stars, or for observing from heavily light polluted locations. This filter's 6 nm is matched to enable premium performance with CCD and CMOS sensors with a very low dark current! Furthermore, a new MFR coating technique allows this 6 nm OIII filter to be used on all telescopes and other instruments with focal ratios up to f/4 without a decrease in performance.



Like all Astronomik filters, the 27 mm OIII 6 nm CCD Filter is parfocal with all other Astronomik filters. Although its thickness is a miniscule 1 mm, this filter is still highly resistant to potential damage that scratching, aging, and high humidity can inflict. Diffraction limited to avoid lessening the optical performance of your telescope. Astronomik filters are delivered in a durable plastic storage container of superior quality.
