The Narrowband series provides line filters with a full width at half maximum (FWHM) of 6.5 nanometres, recommended for optical systems with aperture ratios between f/10 and f/3.5. This range covers most telescopes commonly used by amateur astronomers. The FWHM is also suitable for smaller apertures and offers excellent value for money.
