H-Beta Filter 2 inch from OVL (Optical Vision Ltd, the official Skywatcher distributor in the UK and Western Europe).

This high performance CCD filter transmits only the Hydogen Beta emission line, and therefore is useful for greatly increasing the contrast of objects that glow in the corresponding region of the spectrum, for example the California, Cocoon and Horsehead nebulae.
Recommended for capuring H-beta emitting objects using CCD photography under dark skies.



Available in 1.25" and 2" sizes.
This listing is only for the 2".
Image is for demonstration purposes only: shows both the 1.25 and 2 inch versions.
