Explore Scientific Telescopic Filter

The Explore Scientific Filter Set 4 includes four 1.25 inch colour filters in the colours green, orange, light yellow and dark blue for the moon and planet observation. The filters are suitable from 200 mm (8 inch) opening diameter. The lens filters are made of glass and darken the light coming on the eye or camera sensor and eliminate overradiation. This results in certain details that are visible without the filter. The filters are made of high-quality optical glass and the filter surfaces are plane-parallel, polished and anti-reflective. The filter holders are made of black anodised aluminium. Weight: 44g Box contents: 4 x colour filters; 4 x dust containers
