Baader Filters OIII CMOS Ultra-Narrowband 36mm (70881)
235.96 CHF
Tax included
The OIII filters are designed to allow only light with a wavelength of 501 nanometers to pass through, corresponding to the spectrum lines of double-ionized oxygen. These lines are emitted by planetary nebulae and some emission nebulae, ensuring these objects remain visible while blocking out other light sources. This filtering effect enhances contrast and makes faint nebulae visible for the first time.
