Moon&Skyglow Filter

Moon & Skyglow filter is designed to darken the background sky by blocking light transmission from skyglow 589nm and many street light emissions from artificial light. Its high efficiency preserves image brightness, reveals more details and increases contrast of moon, galaxies, nebulae and globular star clusters.

SII-CCD 6.5nm Deep Sky Imaging Filter

  • Use with H-alpha and OIII-CCD extra narrowband filters (SHO Set) for tricolor CCD astrophotography
  • Narrowband imaging with SHO set can be done with the moon up in heavy light pollution, so your equipment is not sitting dormant for several weeks
  • Hubble look of images can be made by the combination of H-alpha, OIII-CCD and SII-CCD, such as the famous “Pillars of Creation” (M16 Eagle Nebula)

OIII-CCD 6.5nm Deep Sky Imaging Filter

  • Suitable for visual observation on most emission nebulae, planetary nebulae and supernova remnants
  • Hubble look of images can be made by the combination of H-alpha, OIII-CCD and SII-CCD, such as the famous “Pillars of Creation” (M16 Eagle Nebula)
  • Narrowband filter do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.

H-Alpha 12nm Deep Sky Imaging Filter

  • Suitable for viewing on faint emission nebula of H-Alpha line in full moonlight or in severe light pollution
  • Hubble look of images can be made by the combination of H-alpha, OIII-CCD and SII-CCD, such as the famous “Pillars of Creation” (M16 Eagle Nebula)
  • Narrowband imaging with SHO set (H-alpha, OIII-CCD and SII-CCD) can be done with the moon up in heavy light pollution, so your equipment is not sitting dormant for several weeks

LRGB Deep Sky Imaging Filter

  • Work well with debayered monochrome CCD cameras
  • Suitable for deepsky and planetary CCD imaging
  • RGB-imaging allows equal weighting factors for each channel, very important for automated imaging.
  • The ideal raw material for image processing in the sRGB color space is available with LRGB filter set and mono CCD camera.
