  • The best visual and photographic filter for contrast enhancement on all Newtonian and SC-Mirror Telescopes.
  • 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, 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.

Whats the actual size of your 2" filters in "mm" with and without frame/ring?
What step down adapter is suggested from a 52 mm to "-- mm"?

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?

¼" and 2" Neodymium Lunar & Skyglow Filter

With integrated IR blocker and Phantom Group Coating

¼" and 2" Neodymium Lunar & Skyglow Filter

The best visual and photographic filter for contrast enhancement for all Newtonian and SC-mirror telescopes, we have ever offered! Brighter and sharper than ever! Long a dream for all CCD users, our Skyglow & Moon filter with IR Cut coating !! The filter effect is much more neutral in colour and much brighter thanks for our Phantom Group Coating. If you want to escape a city brightened sky - without taking a trip - the new IR Moon & Skyglow filter is the solution.

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.

  • Selective contrast filter, especially suitable for all reflector telescopes.
  • Filters specifics wavelengths especially street lights and skyglow from the Moon without suppressing the visibility of colour and brightness differences. The result is a filter that leaves natural colours intact with RGB significantly enhanced.
  • 95% transmission in the selected spectral ranges.
  • Fits all standard filter threads and can be combined with other filters
  • The filter is also optimised for Astrophotography due to it's full IR-blocking. When used with dSLRs stars are much sharper as the unfocussed IR is blocked.
  • Ultra-hard and durable Ion-beam hardened coatings and may be cleaned anytime without fear, ideally with Baader Optical Wonder Cleaning Fluid.
