Baader IR-Pass Filter (685 nm)

Technical Data:

  • Baader IR-Pass Filer HWB 685nm
  • Reduces the effect of seeing results in a much sharper image.
  • Tip for use: Ideal for imaging and used for the luminosity channel.
  • The effect of use: The normal spectral bandwidth is 400-700nm. This filter starts at 670nm in the deep red, just in the visual range so it can be focussed correctly. At this long-wavelength spectral range, the atmospheric air turbulence (seeing) has a much lower impact on the sharpness. Dark structures on Mars, Jupiter the Moon, and the Sun are thereby rendered much sharper. The luminosity can then be combined with RGB creating a very sharp LRGB image.
  • Highly recommended for any planetary imager.
  • Reflex free anti-reflective and optically polished.
