  2.   Baader Semi APO Filter

    Baader Semi APO Filter

    From: € 80.00 Price excl. German VAT tax (19%): € 67.23
    • Semi-APO Baader filter with IR Blocker
    • A combination of our Moon and Skyglow Neodymium filter with fringe killer coating to deliver an amazing colour-corrected image on achromatic refractors.
    • Virtually neutral-coloured image without the blue and red halos causing the annoying violet fringe. The increase to image contrast is disturbingly great.
    • Reflection-free anti-reflective and optically polished.

  3.   Baader Fringe Killer Color Correction-Filter
    From: € 82.00 Price excl. German VAT tax (19%): € 68.91
    • The fringe killer blocks defocused light in the blue spectrum, as well as in the red part of the spectrum (IR) above 700nm, usually seen in small achromat telescopes.
    • The smaller details on craters of the Moon and planetary surfaces are so much more visible!
    • Planeoptically polished; can be used well before the focal point of the optical system, without any loss of sharpness, as a single filter in front of a binocular for afocal projection with digital cameras.
    • Provides the brightest picture of all industrially manufactured colour error-correction systems. Thus, the Fringe-Killer is a must for small refractors!

  4.   Baader IR-Pass Filter (685 nm)

    Baader IR-Pass Filter (685 nm)

    From: € 79.00 Price excl. German VAT tax (19%): € 66.39
    • Baader IR-Pass Filer HWB 685nm
    • Reduces the effect of seeing resulting in a much sharper image.
    • Tip for use: Ideal for imaging and used for the luminosity channel.
    • The effect of use: The normal spectral bandwidth is 400-700nm. This filter starts at 670nm in the deep red, just in the visual range so it can be focussed correctly. At this long-wavelength spectral range the atmospheric air turbulence (seeing) has much lower impact on the sharpness. Dark structures on Mars, Jupiter the Moon and the Sun are thereby rendered much sharper. The luminosity can then be combined with RGB creating a very sharp LRGB image.
    • Highly recommended for any planetary imager.
    • Reflex free anti-reflective and optically polished.

  5.   Baader UHC-S / L-Booster-Filter

    Baader UHC-S / L-Booster-Filter

    From: € 79.00 Price excl. German VAT tax (19%): € 66.39
    • Visual and photographic UHC-S Nebula filter
    • Ultra High Contrast L Filter blocks city lights and increases contrast of Nebula
    • Planeoptically polished for the highest image quality.
    • Creates a much brighter image than a conventional Nebula filter.

  6.   Baader Neodymium (Moon & Skyglow) Filter

    Baader Neodymium (Moon & Skyglow) Filter

    From: € 79.00 Price excl. German VAT tax (19%): € 66.39
    • The best visual and photographic filter for contrast enhancement for all telescopes, without loss of image brightness!
    • The effect of the element neodymium as filter material is very impressive. When added to optical glass, it enhances contrast, enhances the red colour in the image (especially with Mars and Jupiter) and it darkens the spectral region which is particularly marked by street lamp light, which is the biggest contributor to the nightly "Skyglow".
    • Planoptically polished and MC-coated – with IR-cut coatings!, without any loss of sharpness as a single filter in front of a binocular or be used for afocal projection with digital cameras (far from the focal point!)
    • The IR spectral range is blocked making stars much sharper when used with dSLRs.
    • The Baader Moon & Skyglow Neodymium Filter are two filters in one: Neodymium contrast enhancement filter and UV/IR blocker.

  7.   Baader Solar Continuum Filter 1¼" (double stacked)

    # 2458392

    € 170.00 Price excl. German VAT tax (19%): € 142.86
    • 1¼" Double Stacked Baader Solar Continuum Filter. 8nm / CWL 540nm.
    • Includes 1x AstroSolar® Photo Film OD 3.8 20x29 cm. The filter includes two Baader Solar Continuum Filters in a single filter cell which have been stacked for even higher contrast.
    • Enhances the contrast and reduces the effect of atmospheric turbulence.
    • This filter must be used in conjunction with a Baader Herschel Wedge or Baader AstroSolar® Safety Film 5.0 (not included) for solar observations otherwise equipment damage may occur. The included Baader AstroSolar® Photo Film 3.8 must not be used for visual observation but only for solar photography (e.g. lucky imaging).

  8.   Baader Solar Continuum Filter (540nm)

    Baader Solar Continuum Filter (540nm)

    From: € 80.00 Price excl. German VAT tax (19%): € 67.23
    • Baader Solar Continuum Filter, 10nm / CWL 540nm
    • A must for owners of achromatic refractors. This filter cuts the spectral range transmitting a specific spectral range around 540nm, completely cutting out blue and red wavelengths in an area of the lens system that where the optics are at their sharpest.
    • Enhances contrast and reduces the effect of atmospheric turbulence.
    • This filter must be used in conjunction with a Baader Herschel Wedge or Baader AstroSolar Safety Film for solar observations otherwise eye or equipment damage may occur.
    • Planeoptically polished, non-ageing sealed coating edges.
