Astronomik L-1 UV/IR Block Clip-Filter for Canon EOS R APS-C
Astronomik L-1 UV/IR Block Clip-Filter for Canon EOS R APS-C
Astronomik offers three different ultraviolet (UV) and infrared (IR) blocking filters. These filters block short-wave UV and long-wave IR light for taking images for the luminance channel. The three versions are designed to help you optimize your optical setup to produce the sharpest and most contrast-rich images possible. The luminance channel is critical to a great final image because it provides the most signal, which means the filter should have the highest transmission possible with a wide spectral bandpass across the entire visible spectrum. This combination ensures the highest sensitivity and photon counts on your pixels. However, not all optical instruments or additional optical elements like correctors, field-flatteners, or reducers have a perfect color correction. A Luminance filter with too wide a bandpass can show chromatic aberration of the optical system, resulting in soft or bloated stars and making image processing difficult. To address this, Astronomik offers its line of Luminance filters: the L-1 filter with the widest spectral window, the L-2 filter with a standard spectral window, and the L-3 filter with the narrowest spectral window.
Depending on the color errors of the instruments used, the Astronomik Luminance filter with the widest spectral window should be used.
- L-1 UV-IR Block filter: Ideal for chromatic aberration-free optical systems such as reflector telescopes, where additional lenses are only used to correct image errors, not to change the focal ratio.
- L-2 UV-IR Block filter: Suitable for APO refractors or very good doublets used with their native focal length, reflecting telescopes with focal reducers and RASA telescopes. The transmission is very close to the UV-IR blocking filters used by companies such as Canon and Nikon in their cameras.
- L-3 UV-IR Block filter: Designed for refractors and camera lenses with less-than-perfect color correction to minimize bluish halos around stars.
Canon EOS R APS-C series cameras are an excellent choice for astrophotography. With Astronomik Clip-Filters, you can use our full range of filters with your camera to capture stunning images. Whether paired with a camera lens or a telescope, our clip filters ensure maximum image quality and performance from your setup. Additionally, all Astronomik EOS R APS-C Clip-Filters serve as an excellent dust shield, protecting the sensor during long exposures. If you only need a dust shield without filtering effects, the Astronomik MC-Clear EOS R APS-C Clip-Filter is the right choice. Use Astronomik filters for your Canon EOS R APS-C camera and enjoy marvelous images with an ultra-light equipment!.
Astronomik filters are diffraction-limited, ensuring that the optical performance (resolution and contrast) of your telescope is not compromised. Thanks to the high-precision machining of the glas substrate, all Astronomik filters are parfocal. The wedge errors are far below all common tolerances. Therefore, all issues concerning focal distances and the exact alignment of images from each color channel are effectively eliminated. All Astronomik filters are ideal for modern cameras, including both CMOS- and CCD-based models, ensuring you capture the best possible images with your equipment. Sharpness, contrast, and the absence of any reflections and halos are guaranteed. Even with bright stars in the field of view, nebulae and galaxies will be captured with the finest structures. The Astronomik MFR and MaxFR coatings are designed for optimal performance across a wide range of focal ratios of the optics used. Every Astronomik filter undergoes a rigorous quality control process before delivery.
