Product Details

  • The Oiii Narrowband filter transmits only Oxygen-iii wavelength light, which is found in most nebulae, star clusters, galaxies, and stars. This makes these filters ideal for complex false color imaging of such regions. Oiii filters such as this one are excellent for boosting contrast and are most definitely a must-have for imaging in areas with high levels of light pollution. This particular Oiii filter has a bandwidth of 7nm.
