Polarizer & Neutral Density
conveniently observe overly bright objects / Moon
From: € 48.00 Price excl. German VAT tax (19%): € 40.34
- Baader Neutral Density Filters ND 0.6 / 0.9 / 1.8 / 3.0.
- For perfect energy management during Lunar and Solar observation. Suitable for solar observing only as an additional filter!
- If you need to reduce glare and want to use a filter ahead of the focal point (e.g. before a binocular), then the neutral density filters are just right.
- Fine optical polish results in no loss of sharpness at high magnifications even with a filter position 20-30cm in front of the focal point.
- Phantom Group coated. No ghosting, reflections or stray light.
- Threaded both sides of the glass allows combination with other filters (e.g. Baader Colour Filters).
From: € 42.00 Price excl. German VAT tax (19%): € 35.29
- Baader Polarizing Filter - Ideal filter for solar and lunar observations and contrast enhancement in planetary observations.
- Fits 1¼ or 2" eyepieces/threads and is screwed before the eyepiece
- Adjustable brightness when used with a Baader Hershel Wedge
- Important Note: Polarizer will need additional filtering (eg Herschel Prism or AstroSolar Safety Film) before the eyepiece of the telescope for solar observations.
From: € 80.00 Price excl. German VAT tax (19%): € 67.23
- Baader Double Polarizing Filter - Ideal for solar and planetary observations.
- For solar work in conjunction with Baader AstroSolar Safety Film or Baader Herschel Wedge Prism (never use any eyepiece filter for solar observation without objective front filter).
- Rotatable filter cell allows continous adjustment of brightness for comfortable viewing
- Enhances contrast during planetary observation.
- Non-ageing sealed coating edges.

- 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.
