Product description

CCD or DSLR cameras may also be sensitive to the infrared or ultraviolet regions of the spectrum. This can lead to problems with the colour balance with astrophotography using colour cameras. This problem is solved by inserting a UV/IR cutting filter in front of the camera.


As well as improving the colour balance, the UV/IR cutting filter also improves the imaging properties of lens systems (e.g. refractors). These systems are optimized for visible wavelengths but produce a halo around stars with UV/IR sensitive detectors. This is also eliminated with a UV/IR cutting filter.
Also very suitable for solar observing - sunlight should only be observed through a solar filter or Herschel prism. The additional blocking of harmful UV light by this filter is a very good idea.

Application: Daystar recommends this blocking filter for use with the QUARK series of H-alpha filters. These solar filters are designed for refracting telescopes. When using larger refracting telescopes, this blocking filter should be used in addition to the QUARK solar filter. The filter can be easily screwed into the filter thread of a 2" diagonal mirror, as shown in the illustration on the right. The blocking filter is marked in turquoise in the illustration.
