Astronomik XT filters for wide-angle lenses: The new Astronomik XT filters have been specially developed for astrophotography with wide-angle lenses and deliver sharp star images right into the corners of the image.
Astronomik clip-on filters have been a popular and well-known accessory for astrophotographers around the world for many years. However, when using lenses with very short focal lengths for wide-angle photography, standard clip-on filters can cause aberrations, and the stars in the outermost corners of the image become streaked. To solve this problem, the new Astronomik XT filters are mounted on an extremely thin substrate with a thickness of only 0.3 mm or 0.5 mm, which significantly reduces these aberrations.
Despite their reduced thickness, Astronomik XT filters offer the highest optical quality: they are finely polished, free of streaks, internal stresses and bubbles, and suitable for the most demanding applications.
Astronomik XT filters are manufactured using the same durable coating technology as all Astronomik filters. They are extremely scratch-resistant, insensitive to high humidity and non-ageing. This ensures that they maintain their performance for years to come.
Please note that not all Astronomik filters are available as XT versions, as the manufacture of these extremely thin filters is very complex. Currently, filters are being produced that are ideal for photography with wide-angle lenses.
Clip filters for Canon EOS R and RP full-frame mirrorless cameras: The clip filters can be quickly and easily mounted in the camera body without tools. The filter can be inserted or removed at any time, even on the go or at night. No modification to the body is required to use the clip filters. Removal is done with a small hook, which is included in the scope of delivery.

Astronomik ProPlanet 742 IR-pass filter
Ideal filters for the reception of the moon and planets, notably Mars, with telescopes from 6" (150mm) aperture.
The ProPlanet IR 742 only allows infrared light with wavelengths of more than 742 nm to pass. In this wavelength range the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows much sharper images than are usually obtained from your device and location. Another advantage is that the sky background of advanced dawn is dark and so the filter even allows photography of the planets and the moon at daylight.
Main use
The Astronomik ProPlanet IR 742 cuts off the visible part of the spectrum and allows the light of wavelengths longer then 742nm to pass. Due to this behavior the part of the spectrum that is most sensitive to bad seeing is rejected. This approach does a big improvement to the imaging of planets and the moon. The image is more steady than the image in the visible light with nearly identical exposure times.
Alternative: For very strong seeing and for instruments with an aperture of 10" (250 mm) or more, an Astronomik ProPlanet IR 807 may be useful.
