  • Baader 2" Neutral Density Filter with optical density ND 1.8 - Transmission 1.5% - Reduction factor 64.
  • For perfect energy management during Lunar and Solar observation. Suitable for solar observing only as an additional filter!
  • If you need to reduce glare and want to use a filter ahead of the focal point (e.g. before a binocular), then the neutral density filters are just right.
  • Fine optical polish results in no loss of sharpness at high magnifications even with a filter position 20-30cm in front of the focal point.
  • Phantom Group coated. No ghosting, reflections or stray light.
  • Threaded both sides of the glass allows combination with other filters (e.g. Baader Colour Filters).
