Explore Scientific Filters 2" OIII filter (54041)

96.77 CHF

Tax included

OIII filters allow only light with a wavelength of 501 nanometres to pass through. This corresponds to the spectrum lines for double ionized oxygen. These lines are emitted by planetary nebulae and some emission nebulae, allowing these objects to remain visible while the rest is blocked out by the filter. This effect increases contrast and makes faint nebulae visible for the first time.
