  • 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.

I note that you do not provide either the Neodymium Filter nor the IR-Pass Filter in a version that is 'Square 50 x 50mm unmounted', is this correct?
In relation to both Filters' Wavelength Spectrum Response what alternative Filter(s) do you have that has the nearest spectrum response in the 50 x 50mm unmounted version? Preferably 3mm thickness.
The reason for this enquiry is to have a useful 'Luminesence' filter for Lunar and Planetary Astrophotography when the rest of the filters are for Deep Sky Imaging (Baader CCD Complete Filter Set II 50 x 50mm #2459544).

Hi I have a Canon 5D modified with the stock IR filter removed making it full spectrum imager. I need a standard 2" threaded IR cut filter to block the unwanted IR while leaving the Ha intact, I could purchase your Baader UV-IR-CUT Filter for this purpose but wonder if the Moon and sky-glow filter would serve dual duty to cut the unwanted IR while also preforming as a LPF with the additional benefit of lunar and Planetary enhancement. Lastly would the Moon and Sky Glow filter degrade deep sky imaging at dark sky locations thus making a case for the need of both filters?

1¼" and 2" Neodymium Lunar & Skyglow Filter

Drastic contrast enhancement for all telescopes, without loss of image brightness! This filter is initially based on a development by Carl Zeiss. The effect of the element neodymium as filter material is very impressive. If used as co-mixture to optical glass, it improves the contrast and enhances the red portions of the image (especially for Mars and Jupiter). At night it blocks that part of the spectrum, which suffers most from street lighting – and it blocks the light pollution, also known as „skyglow“. And lastly, the applied UV/IR blocking coating (Luminance-coating - check the spectral trace) cuts all unwanted UV below 400 nm and NIR above 700 nm - this makes it the „sharpest contrast enhancing filter“ for imaging.

Compare with the moon & Skyglow filter before the naked eye, to test the effectiveness. Red and blue colours are extensively strengthened. If you cannot see the GRS (Great Red Spot) due to pollution try this which will allow you to see it.

In order to establish a precise plan area and to maintain the planarity despite the applied forces through the different layers of coating, a high technical effort is necessary. You have to choose from a large amount of raw glass only the best pieces in tension-free annealed quality to even hope for a good final quality may. All too easily, the glass deforms with improper preparation or coating on older evaporation systems. The final product is almost useless, if not greatest of care is taken at every stage of production.

Surface details on Mars, Jupiter and Moon as well as many deep-sky-objects become much more prominent.

  • Selective contrast filter, especially suitable for all reflector telescopes
  • Filters out specific wavelengths, especially those caused by streetlight and most importantly their scattered light which lightens up the night sky
  • Selective blocking retains natural colours intact but with RGB significantly enhanced, differences in colour and brightness persist.
  • 95% transmission in the selected spectral range.
  • Fits all standard filter threads and can be combined with other filters – e.g. the planeoptically
    polished (!) Baader planetary colour filters. This way, you can see fine details better or combine several images with a monochrome camera to achieve colour images.
  • The filter is at the same time optimised for Astrophotography due to it‘s full UV/IR-blocking coating. When used with DSLRs, stars will remain much tighter, because the unfocussed UV and IR parts of the spectrum are blocked out.
  • Planeoptically polished; can be used without problems in front of a binoviewer or for afocal photography – far away from the focus without loosing sharpness!
  • The fine-optical polish and absence of wedge error in the glass ensure perfect sharpness when magnifying more than 200x - while the much cheaper “fire -polished” filter glasses destroy the optical wavefront at high mags
  • Neodymium doped optical glass
  • Coatings Front/Back: 7-layer hard-BBAR-coating / 27-layered dielectrical UV/IR-cut coating
  • Ultra-hard and durable Ion-beam hardened coatings – may be cleaned anytime without fear

The adjacent graph shows you the spectral curve of our Neodymium Moon & Skyglow filters. On the horizontal axis, the wavelength in nanometers, and the vertical axis is the transmission amount (opacity) specified in percent.

The area under the curve is the spectral range that can pass through the filter.

 

The filterholder that adapts to your needs!

The Baader-UFC (Universal Filter Changer) is what you need for „quick-draw“ exchange of filters during imaging and visual observation alike. A myriad of adapters will fit the filter-changer onto almost any telescope. So the core product must never be changed. Just buy another adapter ring when moving on to another camera or telescope.
