IDAS

IDAS Filter from Japan

IDAS filters effectively suppress stray light from cities and thus increase the contrast of astronomical objects. This enables photography and observation of faint nebulae even near cities.

IDAS filters are manufactured in Japan and offer very good optical processing for best possible results. Due to a high quality anti-reflective coating, disturbing reflections and halos around bright stars are significantly reduced.
