Baader Filters OIII CMOS f/2 Highspeed 2" (70917)

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 some emission nebulae, making these objects visible while blocking out other light. This enhances contrast and reveals faint nebulae that were previously invisible.

Description

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 some emission nebulae, making these objects visible while blocking out other light. This enhances contrast and reveals faint nebulae that were previously invisible.

Astrophotography: These filters are ideal for use with monochrome cameras. For the best results, images taken with OIII filters should be combined with those captured using H-alpha and SII filters. This combination produces high-contrast images that clearly show faint nebulae.
