  3. Astronomik - H-Alpha 6nm CCD Filter - 31mm Round Unmounted

    $249.95
    SKU: ASN-HA6-31

    Ships in 3-5 Days

    The Astronomik 6nm H-alpha filter is an extremely narrow emission-line filter for CCD photography. The filter lets the H-alpha light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive. The full width at half-maximum (FWHM) of 6nm is optimized for a maximum contrast between the (H-alpha emitting) object and the background. The contrast gain is much higher than with our 12nm emission line filters but you won’t see as much stars in the resulting images.

  11. Astronomik - OIII 12nm CCD Filter - Canon Full Frame EOS Clip

    $309.95
    SKU: ASN-OIIICCD-XL

    Ships in 3-5 Days

    The Astronomik OIII CCD filter lets the light of double ionized Oxygen emission lines to pass while blocking almost all the remainder of the CCD sensitive light spectrum. The FWHM of 12nm is suitable for most common CCD sensors that allows for the use of fast optical instruments. This filter is recommended mostly for instruments with aperture ratios of 1:3 to 1:15 with 6" or higher aperture diameters. When a CCD is cooled to -15°C, the exposures are limited by the dark current. The 12nm filter assists in providing more available guiding stars for built in guiders.
