An outstanding filter for moon and planets for all telescopes, suitable for observing and astrophotography
♦ Reduction of light green and dark yellow light, thus:
♦ Significant increase in contrast and increase of reddish details for example of Mars and Jupiter
♦ Best filter for the Great Red Spot on Jupiter
♦ No annoying coloration of the image like in normal colour filters
♦ Suppression of street lights for general increase of contrast - sky-glow filter
♦ Fine-optically polished and multi-coated, thus can be used in front of bino-viewers or for photography
♦ Blocks IR radiation at the same time, thus increasing the sharpness of the image
♦ Suitable for 1.25" eyepieces and adapters
♦ Comes in a stackable high-quality plastic filter box
This filter is one of the best planetary filters we know. In the solar system, the filter offers a significant increase in contrast especially on Mars, Moon and Jupiter, but the filter is clearly more versatile. For example, it increases also the contrast of many deep-sky objects like planetary nebulae and diffuse nebulae. The filter can be used photographically without any restrictions.
♦ Selective blocking dampens overexposure, but without suppressing important colour and brightness differences
♦ The transmission in the selected spectral ranges is more then 95%
♦ Fits into all standard filter threads; can be combined for example with the fine-optically polished Baader colour filters for planetary observing. Thus details can be enhanced specifically or detailed planetary colour images can be made with monochrome planetary cameras.
♦ If used with digital cameras, stars and planets are shown significantly sharper, as the IR range is blocked
♦ Fine-optically polished; can be used as single filter in front of a bino-viewer or for a focal projection with digital cameras without any loss of sharpness
♦ No incline in sharpness with magnifications above 200x as with "raw-polished" (flame-treated) glass plates
♦ Substrate (glass): Neodymium doped colour glass
♦ Coating: 7-layer hard-multicoating / 27-layer dielectric UV/IR blocking coating
♦ Ultra-hard and durable Ion-beam hardened coatings may be cleaned anytime without fear
