ProStar 2-inch Hydrogen Beta Filteradd this item to shopping cartThis product is highly recommended
Code: PS-HB2
2-inch (M48) Hydrogen Beta filter for improved visual contrast when observing objects like the Horse Head Nebula etc


The ProStar Hydrogen-Beta filter isolates only the hydrogen-beta line of the spectrum (486nm) in a narrow pass-band just 9 nm wide, providing maximum contrast.

It will allow you to view extremely faint nebulous objects such as the Horsehead, Cocoon and California Nebulae.

This 2-inch (50.8mm) highly polished optical filter produces highly improved visual contrast and is best suited for use with telescopes 200mm aperture or larger.
