1¼ inch neutral density filter with optical density 0.9 - transmission 12.5% - attenuation factor 8x. Can only be used as an additional filter when observing the sun If you need to dampen overradiation and want to use a filter far in front of the focal point (e.g. in front of a binocular), then the neutral filters are just the thing. Thanks to the fine optical polishing of our filters, no loss of sharpening performance can be detected at high magnifications even at a filter position 20 or 30 cm in front of the focal point. Box contents: Baader 1¼ inch grey filter, MC / ND 0.9 (T=12.5%); filter box
