Product description Enhancing the contrast of nebulae emissions by passing only hydrogen alpha light, the StarGuy H-Alpha 7nm Narrowband Filter from Vixen Optics is compatible with telescopes featuring a 2"-diameter eyepiece. The design of this deep red long pass filter passes a narrow, 7nm band of hydrogen for increased contrast and separation of values. By passing H-alpha light and attenuating light pollution wavelengths, this filter is especially well suited to photographing the Horsehead and North America Nebulae, along with other emission nebulae. It is constructed from HB610 tinted glass and polished and coated on both sides to prevent surface reflections and halo effects.
