SVBONY moon filter is a good all rounder filter suited to many applications;including the observation of the moon and planets;a broad spectrum of light transmission means it does not block as much as a deep sky filter
For deep sky photography; use the dual-band filter to enable deep-sky photography in light-polluted cities or under a full moon
Effectively filters out selective wavelengths of low pressure sodium and other man made sources typically used in street lighting;give improved definition of the surface of the moon
The filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space
The SV220 dual band filter reduces light pollution and improves contrast for imaging nebulae.
