Astronomik 1.25"/2" Narrowband Emission Line H-Alpha-CCD Filters w/ 12nm FWHM & MFR Coating (ASK-HALPHA-12NM-CCD)

Astronomik 1.25"/2" Narrowband Emission Line H-Alpha-CCD Filters w/ 12nm FWHM & MFR Coating (ASK-HALPHA-12NM-CCD)Due to the combination of the narrow bandwidth of 12nm and the high transmission of typically 96% the filter gives you an contrast boost, as all unwanted light from other wavelengths than 656nm is blocked form UV up to the IR. This results in an very dark background compared with any filters with a higher bandwidth. The FWHM of 12nm is optimized for typical DSLR cameras with CMOS sensors and CCD cameras with a normal high dark current: With these
