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.
