Baader Contrast Booster Filter 1.25"
A unique filter for many different astronomical tasks – incomparable in acuity. A strong minus-violet filter for achromats, and an EXCELLENT PLANETARY FILTER.
Features
  • Eliminates the color error of economy
  • Refractors

  • Clearly puts the real quality of the lens on display

  • Removes the bluish „hue“ (= lack of
  • contrast) during lunar-, planetary-,
  • solar- and terrestrial observation!

  • Strongly emphasizes 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 color filters, used to
  • bring out detail on Jupiter.
  • Color recognition will be retained!

  • The ultimate in lunar filters! Moon
  • (and Sun!) appear much more natural in
  • color (with a slight yellowish tint),
  • compared to the usual low priced dark
  • green Moon-filters, usually offered for
  • beginners telescopes.

  • Completely removes distracting false
  • color and the resulting smeared
  • and 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
  • Airglow is removed from the
  • telescopic image.

5 of 5 I love it! November 7, 2022
Reviewer: Joseph Adams from Columbus, OH United States  
I gasped "Wow!" when seeing Jupiter with this filter! I'm using it all the time for planetary viewing. I haven't tried Mars yet, but it only slightly enhances viewing of the Moon and Saturn. Still, it's better than nothing. With Jupiter, though, it makes an incredible difference; it brings out so many more of the cloud bands and so much more detail within those bands.

5 of 5 Baader Contrast Booster September 19, 2022
Reviewer: MARK from United States  
I have used this filter with my 8" f/6.1 reflector and an assortment of Brandon and orthoscopic eyepieces for observation of Jupiter, Saturn, and Mars. The cloud belts on Jupiter are more defined than an unfiltered view and additional cloud belt detail is revealed. It helps somewhat with the definition of Saturn's ring system. Mars is where this filter really helps the most! An unfiltered view of Mars is often too bright and washes out detail. Most nights where I live the seeing will not permit anything north of 250x. With the addition of the Baader Contrast filter surface markings and the polar cap are readily apparent at lower mags.

5 of 5 Baader Contrast Booster Filter December 6, 2020
Reviewer: Edward Look from Westbury, NY United States  
Well, I haven't had the opportunity, literally due to lack of clear nights, to test it out.  I will admit everyone whom I saw who wrote about it liked it, particularly when used on Mars.  However, the ordering was quick and easy and it was shipped to me very quickly with no issues.  Why did I choose EyepiecesEtc.com?  Don Pensack, proprietor is an informative and insightful contributor to Cloudy Nights' forums and why not patronize someone's shop, the owner of which is one of the crew at Cloudy Nights?  If I can, I might add to this after I get a chance to test the filter out.
