Tele Vue

Produced in partnership with Astronomik of Germany with the tight tolerances and exacting standards that both companies are known for, the 2" Tele Vue Bandmate Nebustar Type II UHC Filter is designed as a superior general-purpose nebula filter that increases contrast and enables better nighttime viewing of nebulae by blocking a majority of the wavelengths of light pollution in order to gain increased detail. Unlike conventional UHC filters, this one also blocks red wavelengths that are normally allowed to pass through and interfere with clear viewing.This filter passes the H-beta emission lines at 485nm and oxygen emission lines at 505nm with a peak transmission of greater than 96% to brighten nebulae while darkening the background sky for increased contrast and definition of your subject. This version of the Nebustar filter is set in a 2" aluminum ring to enable its use with larger eyepieces and accessories.
