Why to use a UVenus filter?
As we know, Venus has very thick atmosphere, and the clouds has very high reflection of ultraviolet. Using a UVenus filter will enhance the details of Venus. Our UVenus filter has 80% peak transmittance and OD5.0 off-band blocking, it will improve the imaging effect a lot!
UVenus filter using color optical glass and over 100+ multi-coating process, to make sure this filter has very good quality.
Multi-coating and color optical glass, make this filter has very beautiful color on both sides.
