Hydrogen-alpha 3.0nm passband. This filter is designed for non-solar imaging, and is used to image deep-sky objects that emit in the h-alpha passband. It is too wide for solar-prominence viewing, but is ideal for deep sky.
It is in perfect condition. It was kept in a CFW8 filter wheel.
$200 shipped
