Explore Scientific 1.25" H-Beta Nebula Filter

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 artificial light) and only the emission line of hydrogen beta will pass.

The Explore Scientific 1.25" H-Beta Filter has a transmission of 94.5% from 478nm to 496nm. Peak transmission is 489nm. This filter is mounted in a 1.25" metal cell and fits all standard 1-1/4" eyepieces and filter wheels.
