  1. Astronomik - CLS Light Pollution Filter - 1.25" Mounted

    $69.95
    SKU: ASN-CLS-1

    Ships in 3-5 Days

    The Astronomik CLS is an excellent filter for black & white and color imaging of nebulae, galaxies and star clusters with astronomical instruments of any size. By blocking the spectral lines of mercury and sodium-vapor lamps, and letting the largest part of the visible light and H-alpha emissions pass, the CLS filter will effectively block out most surrounding light pollution, eliminating that annoying orange glare.

  2. Optolong - CLS-CCD Filter -1.25" Mounted

    $96.00
    SKU: OPO-CLSCCD-125

    Ships in 3-5 Days

    The Optolong CLS-CCD filter will boost contrast and increase visibility of faint outer regions on most emission nebulae, planetary nebulae, and supernova remnants from light polluted areas when photographed with a color imaging camera.

  3. Optolong - Moon SkyGlow Filter - 2" Mounted

    $70.00
    SKU: OPO-MSG-200

    Ships in 3-5 Days

    The Optolong Moon and Skyglow Filter is ideal for both visual and photographic usage. You'll see a darker background sky because of the obstruction of natural skyglow at 589nm wavelength and in emission from lights that cause artificial light pollution.

  4. Optolong - CLS-CCD Filter - EOS Full Frame Clip

    $135.00
    SKU: OPO-EOSFF-CLSCCD

    Ships in 3-5 Days

    The Optolong CLS-CCD filter will enhance contrast and increase visibility of faint outer regions on most emission, planetary, and supernovae remnant nebulae from light polluted locations when photographed with a color imaging camera.

  5. Optolong - L-Pro Filter - 36mm Unmounted

    $168.00
    SKU: OPO-LPRO-36U

    Ships in 3-5 Days

    The Optolong L-Pro filter delivers better color balance by maximizing transmission band, permitting you to create pictures of broadband objects with emission spectral lines.

  6. Optolong - CLS Filter - Nikon D5000/D5100 Clip

    $109.00
    SKU: OPO-NIKD5-CLS

    Ships in 3-5 Days

    The Optolong CLS filter is ideal for both visual and photographic applications in locations that experience the effects of artificial light pollution. Since the City Light Suppression Filter has a wider pass-band than the popular UHC, or Ultra High Contrast filter, many amateur astronomers favor its use when observing in mild to moderate light pollution.

  7. Optolong - CLS Filter - Nikon D7000/D7100 Clip

    $109.00
    SKU: OPO-NIKD7-CLS

    Ships in 3-5 Days

  9. Optolong - CLS-CCD Filter - EOS APS C Clip

    $155.00
    SKU: OPO-EOSAPS-CLSCCD

    Ships in 3-5 Days

    The Optolong CLS-CCD filter will enhance contrast and increase visibility of faint outer regions on most emission, planetary, and supernovae remnant nebulae from light polluted locations when photographed with a color imaging camera.

  10. Optolong - L-Pro Filter - 50mm Unmounted

    $219.00
    SKU: OPO-LPRO-50U

    Ships in 3-5 Days
