These Baader neutral density filters are ideal for viewing the Moon or planets where you want to reduce the brightness or glare leading to a more comfortable viewing experience. The filters can also be used as an additional filter to the filters used in Baader’s Herschel Wedge.
Each filter is finely and accurately polished meaning there is no loss of image sharpness even at high magnifications. The filters are coating with Baader’s Phantom Group Coatings (PGC) which results in no ghosting, reflections or stray light – all can lead to an poorer overall image. The filter housings are threaded on both sides so other filters can also be used (stacked).
