Feature
●5 planet colour filters: 5 planetary filters in red, orange, yellow, green and blue show details, emphasise features and sharpen the contrast of Mercury, Mars, Venus, Jupiter, Saturn, moon and other celestial objects
●Variable polarising filter: two rotating variable polarising filters change the light transmission from 40% to 1%. They reduce reflection and glare, darken the sky background and enhance visual contrasts to highlight planets and stars. No chromatic aberration
●Combine to get a variable ND filter: If you stack two polarising filters together, you get a variable ND2 2000 ND filter that can be used freely on the telescope without affecting the focal length and can help you capture brilliant star flows. Please note: the thinner polarising filter must be mounted underneath the ring polarising filter
●UHC filter and moon filter: the UHC filter (ultra high contrast) minimises artificial light pollution such as street lights for sharp fog vision in urban and rural areas. The moon filter with 13% transmission allows only 13% light transmission to increase contrast and moon features. The moon and starlight filter can block unwanted light wavelengths of 589 nm and improve the observation of the night sky in urban and rural areas
●10-piece telescopic filter set: This telescopic eyepiece filter set contains 5 x planetary colour filters, 2 x variable polarising filters, 1 x UHC filter, 1 x moon and starlight filter and 1 x 13% transmission moon filter to improve astronomical observation and photography
