About
A 12 nm narrowband H-alpha filter for imaging HII regions from light-polluted or dark sites, clipping into the Canon EOS full-frame body ahead of the sensor so it works with any lens and keeps infinity focus. It doubles as a dust shield for the sensor during long exposures. MFR coating, Standard substrate.
