MrStarGuy 1.25" H-Alpha 7nm Narrowband Filter
Key Features
  • Deep Red Long Pass Filter
  • Ideal for Photographing Emissions Nebula
  • Enhances Contrast and Clarity
  • Coated and Polished HB610 Optical Glass
Enhancing the contrast of nebulae emissions by passing only hydrogen alpha light, the H-Alpha 7nm Narrowband Filter from MrStarGuy is compatible with telescopes featuring a 1.25"-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.
