About
A wider-passband companion to the UHC, aimed at emission nebulae and comets under light-polluted skies with smaller apertures. Its 45 nm FWHM passes more starlight than the UHC while still blocking typical streetlight emissions and airglow. Clip-in for Sony alpha 7 bodies, Standard substrate.
