Baader Filters OIII CMOS f/2 Highspeed 1.25" (70914)

189.94 $

Tax included

OIII filters allow only light with a wavelength of 501 nanometers to pass through. This corresponds to the spectral lines of doubly ionized oxygen. These lines are emitted by planetary nebulae and certain emission nebulae, making these objects visible while blocking out the rest of the light. This significantly enhances contrast and makes faint nebulae observable for the first time.

Tax included

OIII filters only permit light with a wavelength of 501 nanometers to pass through. This corresponds to the spectral lines of doubly ionized oxygen. These lines are emitted by planetary nebulae and some emission nebulae, allowing these objects to remain visible while the filter blocks out other light. This enhances contrast and reveals faint nebulae that were previously invisible.
