    Baader Fringe Killer Optically Polished Filter : The Fringe Killer filter is designed for use with not-corrected achromatic refracting telescopes to perform well into the violet and deep red portions of the spectrum. It is a multi-bandpass filter transmitting most light in the visual spectrum while attenuating much of the light in the violet portion of the spectrum. It also blocks light in the infrared region for CCD imaging, doing all of this while passing a high percentage of the critical yellow green portions of the visual spectrum. The Fringe Killer rejects almost all below wavelengths of 420nm - in the violet portion of the spectrum, while blue light from 420 nm to about 480 nm is attenuated by about fifty percent. The filter enhances contrast, making the objects appear sharper and more clear particularly when observing the brightest objects like the moon, planets and very bright stars. This filter is not at all necessary for use with reflecting or well made apochromatic telescopes. Nor is it beneficial for visual uses with the faint extended objects (nebulae, etc.). Plasma assisted, hardest, scratch proof and water impermeable dielectric coatings of almost 50 coating layers on either side pertains to the carefully designed to extend equal tension onto either side of the substrate. The ion beam deposited coatings on both surfaces are durable and scratch resistant. They will not degrade over time. When combine with Nemodymium Moon & Skyglow filter provides breathtaking contrast on lunar and planetary surface detail. The 31.7mm sized filter will thread into conventional slip fit eyepieces or accessories with the common 1.25" inch threading.
    Baader Fringe Killer Optically Polished Filter is available at Microglobe at discounted price. Microglobe is largest online sport optics store of the UK.
