The Baader contrast filter booster will help sharpen up your stellar images, boosting contrast, emphasising lunar, Martian and Jovian surface details and cutting down on visible light pollution. The filter is especially useful in economy refractor telescopes, where it can aid in the correction of colour aberration.
  • Eliminates the colour error often present in economy Refractor telescopes
  • Clearly puts the real quality of the lens on display
  • Removes the bluish hue (and lack of contrast) during lunar, planetary, solar, and terrestrial observation
  • Strongly emphasises surface detail on Jupiter and Mars. If you have never seen the GRS (Great Red Spot) on Jupiter - with this filter you will
  • Over 95% transmission - provides a bright, brilliant image compared to the usual dark green colour filters, used to bring out detail on Jupiter. Colour recognition will be retained
  • The ultimate in lunar filters. The moon appears much more natural in colour, with a slight yellowish tint, compared to the usual low priced dark green Moon-filters, usually offered for beginners telescopes
  • Completely removes distracting false colour and the resulting washed out image details. You have never ever seen the Moon or the Sun (with AstroSolar Safety Film) so tack sharp in an economy priced telescope
  • Blocks atmospheric 'stray light' (skyglow). Sky-background turns into pitch black
  • Fits each and every standard filter thread; Combines with the (planeoptically polished) Baader Infrared Cut-Filter. In this combination all blue scatter as well as unfocused near infrared light is completely removed - an absolute MUST for digital imaging
  • Planeoptically polished, suitable for being used in front of a binocular viewer, or for afocal image projection during digital imaging (way in front of the focal plane!)
  • No deterioration of resolution with magnifications of 200 x and more - as with 'raw polished' (flame polished) glass
  • Substrate (glass melt) Neodymium doped glass coating (rear face) 7-layer hard-multicoating, featuring 0.25% reflection
  • Coating (front face) 23-layer dielectric long pass blocker
  • Ionbeam hardened coatings on both faces, absolutely scratch resistant - may be cleaned any time without fear
  • A significant part of city light air pollution, as well as atmospheric skyglow is removed from the telescopic image
