Precisely ground, polished, and individually coated to ensure consistency for bandpass centering, transmission, and out-of-band blocking, this round 36mm Baader Premium Narrowband 8nm S-II CCD Filter from Alpine Astronomical is ideal for imaging in the deep red light of the 772nm Sulfur-II bandwidth.

Its short 8nm bandpass isolates the S-II wavelength, blocking all others, allowing users to capture the emission line regardless of moon phase and light pollution. The anti-reflection coatings are designed to prevent halos and are uniformly layered to prevent physical deformation of the optically flat substrates. When used in tandem with the other two most popular wavelengths of h-alpha and oxygen-III, users are able to concentrate on three distinct colors to produce brilliant composite images of the sun, nebulae, planets, and other astronomical objects.

This filter is specifically designed for use on imaging cameras and is not safe or intended for direct solar viewing. Using this filter for direct solar viewing can result in serious eye injury, up to and including blindness.
