Product description

Astronomik XT filters for wide-angle optics: With these filters, you can achieve beautiful star images right into the corners of the image, even with extreme wide-angle shots.

With other Astronomik filters, the image quality in the corners of the image is limited at short focal lengths (wide angle): Although the filters consist only of a one-millimetre-thick glass plate that carries the filter layers, this plate causes aberrations with certain types of short-focal-length lenses, and the stars are pulled apart into streaks.

Astronomik's XT filters are mounted on an extremely thin carrier substrate that is only 0.3 millimetres thick. This reduces "star streaks" in the corners of the image to a minimum.

The extremely thin carrier substrate of the XT filters is, of course, finely polished, stress-free and meets the highest demands of astrophotographers worldwide in every respect.


Despite this ultra-thin glass, Astronomik XT filters feature the same coating technology found in all Astronomik filters: completely scratch-resistant, moisture-resistant and non-ageing. The filter will retain 100% of its performance even after many years.

This Multicoated (MC) glass serves as dust protector or to keep your system parfocal with other Astronomik filters.

This filter should be used if the focal plane of your imaging system should stay in the same place as with other Astronomik filters in place. The multicoating prevents you from unwanted reflections. It blocks neither IR nor UV.

The second main application is dust protection of your system (telescope or camera). As the filter doesn’t modify the spectral transmittance of your system it doesn’t alter the colors. It’s great for keeping all dust away from your optics or sensor.

Lots of Astronomik MC Clear filters in custom diameters are sold to camera manufacturers worlwide. They like the great coating and scratch resistance!

A bit of help with your selection:

  • As a first filter, we recommend the Astronomik CLS filter. This filter suppresses artificial light pollution and natural airglow. By using this filter you get a dark-sky background and can therefore use much longer exposure times to make fainter objects visible. The filter is optimised in such a way that objects are reproduced in their natural colours. Important: the simple CLS filter has no built-in IR-blocking. Therefore you will need the CLS-CCD filter for an astro-modified camera!
  • A good choice for working in locations with really heavy light pollution is the Astronomik UHC filter. The transmission curve of this filter only allows the light of the H-beta, OIII, H-alpha and SII lines to pass through. The background suppression is significantly stronger than with the CLS, however this filter works only for gas nebulae! Star clusters and galaxies are largely filtered out.
  • For a more in-depth introduction to astrophotography, we recommend the OIII, H-alpha and SII emission lines filters, available with full width at half maximum of 6nm or 12nm. With these filters you can create detailed images of faint objects even from locations with extreme light pollution and a full Moon high above in the sky. Images in these narrow emission lines are not naturally coloured.
  • For the owners of astro-modified cameras we offer the Astronomik OWB filter: OWB stands for "original white balance". The filter corrects the displaced colour reproduction of a converted camera so that it can also be used for normal every-day photography, without having to revise every image on the computer.

Please note: In principle, all camera lenses can be used with the Clip-Filter - i.e. Canon EF lenses or camera lenses from other third party manufacturers such as Sigma, Tamron, Tokina, Walimex etc. However, the use of clip-filters with Canon EF-S lenses is NOT possible!
