Planeoptically polished for the highest images quality. Produces a much brighter image with superb contrast than a conventional Nebula filter. Excellent for openings from 100mm.
A new class of LPR Nebula filters finally delivering the happy medium, with enough light for smaller telescope openings at the same time with the high contrast of classical UHC filter.
Light pollution from street lights is blocked carefully. The filter is the sensible addition to all previous deep sky and UHC filters. Both for visual as well as photographic use.
All filters produce a brighter image and are optically polished with ultra-hard dielectric coatings. They are absolutely scratch resistant and can be cleaned as often as needed, ideally with Baader Optical Wonder Cleaning Fluid.
