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

    # 2458392

    € 180.00 Price excl. German VAT tax (19%): € 151.26

    • 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).

  4. Baader Solar Continuum Filter (540nm)

    Baader Solar Continuum Filter (540nm)

    From: € 85.00 Price excl. German VAT tax (19%): € 71.43
    • 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.

  5.   Baader IR-Pass Filter (685 nm)

    Baader IR-Pass Filter (685 nm)

    From: € 90.00 Price excl. German VAT tax (19%): € 75.63
    • 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.

  6.   Baader 7.5nm Solar Continuum Filter (540nm)

    Baader 7.5nm Solar Continuum Filter (540nm)

    From: € 118.00 Price excl. German VAT tax (19%): € 99.16
    • Baader 7.5 nm Solar Continuum Filter, CWL 540nm
    • A must for owners of achromatic refractors. This narrowband-filter cuts the spectral range where lens optics draw sharpest and contrastiest. The Baader Solar Continuum Filter lets you use the full power of your telescope.
    • Enhances contrast and reduces the effect of atmospheric turbulence (in combination with white light solar filters)
    • Enormous contrast gain in monochrome photography even on apochromatic systems
    • Important note: The Solar Continuum Filter must be used ONLY with additional filtering (e.g. Baader Herschel prism or AstroSolar Safety Film)

  7.   Baader U-Venus-Filter (350nm)

    Baader U-Venus-Filter (350nm)

    From: € 239.00 Price excl. German VAT tax (19%): € 200.84
    • Baader U-Filter (Venus and UV) 350nm.
    • Transmission peak approx. 80% at 350nm, bandwidth 60nm (320-380nm), completely blocking the entire spectral range from 200nm to 1120nm.
    • Dielectric multi-coating on optically polished Schott Glass.
    • Enables imaging in the deep UV spectral region. A "breakthrough" for imaging the planet Venus! Allows amateur astronomers to capture cloud structures of the Venusian atmosphere.
    • Successful astro-application of this filter requires a suitable UV-sensitive lucky imaging camera module (i.e. SKYRIS 274M) with at least a telescope of 5" diameter (a telescope with an 8" diameter is recommended).
    • Non-astronomical applications possible: e.g. check for paint damage on cars or state of health of plants and much more. Read more in the detailed description or with a translate tool on this (german) test review: Baader-U" in the "terrestric" Photography

    • The calcium filter Gen-II must NOT be used in the light path WITHOUT pre-filtering.
    • Visual observation is not possible with the calcium filter, as the eye is practically blind in this part of the spectrum. Never point the telescope directly at the sun with only the calcium filter (without an additional attenuation filter).
