Description
H-Beta - Hydrogen is the most abundant element in the universe and many nebulae glow in the light of H-beta. This line filter blocks all other wavelengths (and thereby nearly all of the artificial light) and only the emission line of hydrogen beta will pass. This filter fits all standard 2.0-inch eyepieces and filter wheels.
