These filters are the result of many years of development and experience in the use and production of optics using the very latest coating technologies. Baader Planetarium filters incorporate features that result in performance and robustness not present in any other competing filter, yet at very reasonable prices.
Baader 1.25" Neutral Density Filter with optical density ND 1.8 - Transmission 1.0% - 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).
