Filters moon filter 1.25"

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.
