Astronomik H-Beta CCD Filter

The Astronomik H- CCD filter is designed for CCD Imaging of gas nebulas with larger scopes. Due to the extreme small band pass of the H- line, the filter will produce a maximum increase of contrast even under best observing conditions. At faint H-II nebulas the Astronomik like the horsehead nebula the H- filter often makes the gain, that decides if the object can be seen or not. With the Astronomik H- you will be able to see the horsehead nebula with scopes of 10"...12" aperture under good skies.
