Baader Contrast Booster Filter 2"
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 Best filter for Mars August 4, 2020
Reviewer: Vishal Kasliwal from Sunnyvale, CA United States  
Awesome filter! This filter boosts contrast on Mars quite considerably and makes fine detail visible. Also good for Jupiter and really good for Saturn.
