Baader Planetarium Solar Continuum Filter (540nm) 1,25″
Two-inch mount filter for solar observation at the 540-nanometer wavelength with a 10-nanometer bandpass.
The use of this filter always requires a previous filter of the solar sheet type or Solar glass from our Seymur Solar series.
It enhances the contrast of the Sun's surface and reduces atmospheric turbulence.

The Solar Continuum filter is designed to enhance the visibility of solar graininess and sunspot detail.
By transmitting a specific region of the spectrum free of absorption lines, centered around 540 nanometers, the filter enhances contrast and reduces the effects of atmospheric turbulence.
The Solar Continuum filter works well on all types of telescopes, both for visual observation and photography.
In the case of SC telescopes and achromatic refractors, the filter is particularly beneficial as it completely excludes red and blue wavelengths by focusing on the visible spectral region where the telescope's optics are free of chromatic aberration.
In digital photography it is recommended to combine the filter with a UV/IR type to block infrared wavelengths.
The Solar Continuum must always be installed after the previous filter to avoid damage to the vision or the telescope.
