BAADER CONTRAST- BOOSTER

BAADER CONTRAST- BOOSTER

The Baader Contrast-Booster is specially designed to improve Refracting telescopes- to provide a professional replacement for the simple "dark green" Moon Filters made of "raw polished" glass.

Properties:

  • Eliminates the colour error inherent in popular 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 colour filters, used to bring out detail on Jupiter. Colour recognition will be retained!
  • The ultimate in lunar filters! - Moon (and Sun!) appear much more natural in colour (with a slight yellowish tint),
  • Removes distracting false colour 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!
  • Help to reduce atmospheric "stray light" (skyglow).
  • Fits standard filter thread;
  • No deterioration of resolution with magnifications of 150x and more - as with "raw polished" (flame polished) glass!
  • Substrate (glass melt): Neodymium doped glass
  • Coating / rear face: 7-layer hard-multicoating, featuring 0,2% 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

BAADER NEODYMIUM

BAADER NEODYMIUM & IR Cut filter

Drastically improved contrast for all reflector telescopes, without loss of bright-ness!

Properties:

  • Transmits a maximum of light , while blocking unwanted skyglow and many street light emissions.
  • Especially effective on smaller telescopes which cannot benefit from expensive narrow-band nebula filters due to the huge light-loss involved.
  • Unique selective blocking feature of the NEODYMIUM element greatly reduces glare, without reducing recognition of important colour and brightness variations.
  • Transmission within the selected wave bands exceeds 95%.
  • Fits all standard filter threads,
  • Combined with an UV/IR-Cut-Filter for all CCD and digital camera work. This combination works extremely well due to cutting all unfocused light an absolute MUST for digital imaging.
  • Retains full image resolution even at highest magnification, or during eyepiece projection work
  • Ultrahard and durable Ion-beam hardened coatings, may be cleaned anytime without fear.
  • No image degradation as with flame polished filters.

BAADER Fringe-Killer

BAADER Fringe-Killer

The BAADER Fringe-Killer Filter minimizes unwanted blue fringing, comparable to a Minus-Violet-Filter, while retaining a very pleasing color balance.

Properties:

  • The brightest image of all color-correcting devices in the industry, makes the Fringe-Killer a must for even the smallest of refracting telescopes.
  • Removes blue fringing as well as RED fringing above 656 nm!
  • Breaks the intensity of the devastating false blue colour in a completely new way, never ever before manufactured as astronomical filter.
  • 50% transmission in the blue spectral region from 450 nm to 480 nm being much more complex to produce than even the narrowest of all Nebula Filters.
  • Retains the highest light transmission of all known colour correcting devices be it filters or lenses in all important deep sky wavelengths from 486/501 up to 656 nm. LIGHT is the hottest commodity for high magnification work.
  • Built-in Infrared Blocker, ranging from 656 to 1150 nm, makes it the perfect tool for CCD work, as well as afocal projection-photography with digital cameras for Moon & Planets.
  • Subtlest of colour variations remain visible in planetary surface detail, due to the excellent colour balance.
  • Combine with our NEODYMIUM Moon- & Skyglow Filter # (with Phantom-Group-Multicoatings) for breathtaking contrast on lunar and planetary surface detail!
  • Planoptically polished, means perfect sharpness, even when mounted way in front of a binocular viewer, or during afocal projection (digital imaging).
  • No deterioration of resolution with magnification at 300 times or more as it would happen with the usual flame polished (raw polished) glass, commonly used for all sorts of filters!
  • Coating: Plasma assisted, hardest, scratch proof and water impermeable dielectric coatings of almost 50 coating layers on either side, most carefully designed to extend equal tension onto either side of the substrate in order to retain a highest quality optical figure.
  • Will make the performance of a simple f/8 economy refractor look like a classic f/15 Fraunhofer-Achromate. See it to believe it!

Baader UV-IR-Cut-Filter

Baader UV-IR-Cut-Filter

The only infrared blocker in this price range featuring a planoptically polished substrate, parallel to within 30 seconds of arc!
In combination with the unique properties of the Baader-Contrast-Booster™ the resulting spectral window eliminates all known effects of image deterioration - an absolute MUST for digital imaging.

Baader IR-Pass Filter

Baader IR-Pass Filter

Baader Planetarium delivers the latest tool in the planetary imager's bag of tricks. The Baader IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. Some of the world's best amateur planetary images have been taken with this technique. Suitable for digital imaging only.

Baader UHC-S Nebula Filter

Baader UHC-S Nebula Filter

The UHC-S delivers a darker sky and improved contrast over typical broadband 'Deep Sky Filters', but without sacrificing all the stars like other 'UHC' filters. The moderate 60nm passband and extreme efficiency makes this filter great for smaller scopes as well as the giants. Ideal for imaging, too (with >99% transmission of H-Alpha).

The new Baader AstroSolar™ Safety Film (neutral density=5)

Baader AstroSolar™ Safety Film (neutral density=5)

Baader Planetarium is a safety film for solar observation. It is made for the construction of high-quality objective-filters for observing the sun with telescopes, binoculars, camera or video-lenses. This foil is CE-tested and reduces the intensity of sunlight by 99.999%.

Baader Planetariums AstroSolarTM safety film is a specially manufactured streak- and blister free foil. It attains the optical performance of plane parallel glass filters. The base material is not "Mylar"!. The basic development of this film was made in laboratories for nuclear- and particle physics.

High density coatings on both sides of the foil ensures a highly uniform filtering, while neutralizing the occasional microscopic holes in the coating. The image of the sun is extremely contrasty and of almost neutral colour.
