High quality, plane-parallel glass filter. Reduces the Moon’s glare to a manageable level.
For screwing into 1.25″ eyepieces.
Our expert comment:
We measured 30% light transmission (corresponding to optical density ND05), which means the filter is perfectly appropriate for telescopes with rather small diameters. For larger telescopes, i.e. 200 mm and more, a filter with less transmission (eg. 13%) would be more effective. In this case, we would recommend, for instance,m the Omegon moonfilter.“] A maximum of flexibility is achieved with a [cms://shop/p_id=7399 “variable polarizing filter.
