Baader: Neutral Density Filter 1.25", Multicoated / ND 0.9
Baader 1.25" Neutral Density Filter with optical density ND 0.9 - Transmission 12.5% - Reduction factor 8. 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).
