Aliexpress UK
Item model number: 2458391. This filter is able to boost contrast and reduce the effects of atmospheric turbulence. Due to the narrow bandpass and complete blockage of longer and shorter wavelengths make it superior to standard green color filters for testing refractors at their center design wavelength.

Baader 7.5 nm Solar Continuum 2" Filter, CWL 540nm with 2" screw-in thread. Lens systems - including those of apochromats, catadiopters or eyepieces - are traditionally optimized for the spectral range around 540nm, since this is where our eye has the highest sensitivity.

Lens systems - including those of apochromats, catadiopters or eyepieces - are traditionally optimized for the spectral range around 540nm, since this is where our eye has the highest sensitivity. Compared to the previous model with a 10nm half-band-width, this filter has a half-band-width of only 7.5nm, which increases the contrast even more.
