Astronomik Deep Sky Colour Filter (Standalone)

Astronomik Deep-Sky Colour Filters Astronomik offers a high-end series of RGB filters: the Astronomik Deep-Sky RGB filters are specifically designed to meet the needs of modern astrophotographers, delivering maximum image quality with all CMOS and CCD cameras. Use the Astronomik Deep-Sky RGB filter set to achieve images with unparalleled sharpness, contrast range, and vibrant colors. These filters are recommended for all modern CMOS and CCD cameras from companies such as ZWO/ASI, QHY, QSI, SBIG, ATIK, and ALTAIR. If you aim to capture the most beautiful images with your equipment, the Astronomik Deep-Sky RGB filters are the perfect choice! The Astronomik Deep-Sky RGB filters are the result of extensive, years-long research and development. We are proud to offer you the best RGB filters currently available for deep-sky imaging. The transmission range of these three filters is designed to allow the important emission lines in deep-sky photography to pass through, providing strong signals and vivid colors. Raw images captured with the Astronomik Deep-Sky RGB filter set can be easily combined into a stunning composite. Feedback from our customers has been extremely positive, mutually reporting smaller, sharper star images compared to conventional filters. This aligns with one of our primary development goals: achieving the highest contrast with pinpoint star images. During the development and testing of the Astronomik Deep-Sky RGB filters, we focused on the sensitivity curves of popular cameras used by modern astrophotographers. Instead of relying on manufacturer specifications, we conducted extensive measurements in our development lab. The result is excellent, balanced color reproduction and the best color contrast with all common sensors. The transmission characteristics and coating technology of the Astronomik Deep-Sky RGB filters ensure that no halos or reflections are visible. Even with bright stars in the field of view, nebulae and galaxies will be captured with the finest structures. In addition to the Astronomik Deep-Sky RGB filters, we offer three different Luminance filters (Astronomik L-1, L-2 and L-3 UV-IR Block). The different transmission ranges of each Luminance filter are designed to match the color correction of different telescopes in order to obtain the sharpest image with any optical design and camera, even with instruments with less-than-perfect color correction. Additional note for photographers and observers under light-polluted skies For those working under light-polluted skies, consider using the Astronomik CLS CCD filter instead of a Luminance filter. The Astronomik CLS CCD filter captures luminance signals while effectively blocking high- and low-pressure sodium (Na)- and mercury (Hg)-vapor lamp lines, resulting in significantly less background noise. This substitution has been highly praised by customers worldwide, who report the advantages of the Astronomik CLS CCD filter for the luminance channel, making color deep-sky photography feasible in many regions. Suitability of the Astronomik Deep-Sky RGB filters CMOS and CCD photography: Excellent for deep-sky imagingWebcam and video: Reasonable, used as a color filter for imaging planets Size of filter Astronomik filters come in a wide range of standard sizes, both mounted and unmounted, to suit various optical setups and cameras. Technical Data • Maximum transmission typically 95% or better • All Astronomik Deep-Sky RGB filters have IR- and UV-blocking • Glass thickness: 1mm (except Astronomik OWB Type 3 and XT filters) • Finely polished optical glass, free of any striae, residual stresses, and bubbles • Extremely scratch-resistant and durable coating • Completely resistant against high humidity and aging effects • Astronomik MFR coating (Astronomik Deep-Sky RGB, UV-IR Block L-1, L-2, L-3, and Narrowband-Emissionline filters) • Parfocal with other Astronomik filters • Diffraction-limited • Optimized spectral windows • Delivered in a high-quality, long-lasting filter box • Made in Germany 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.
