No 25 Full Red colour filter to fit 1.25" filter threads. A great filter for Mars, Jupiter and Saturn especially with larger telescopes! Similar in performance to the No 23a filter but delivering higher contrast. To a certain extent it provides the higher contrast views at the expence of image brightness and performs at its best with instruments of 6" aperture or greater. The filter is made of top quality optical glass and is mounted in a black anodised aluminium holder and is supplied in plastic storage case.
