• The new Astronomik Deep-Sky RGB filter set is specially designed for the needs of demanding astrophotographers to achieve maximum image quality with all CCD cameras. Use the Deep-Sky RGB filter set to achieve images with unparalleled sharpness, contrast range and vivid colours.
• The transmission range of the filters is designed to allow the emission lines that are important in deep-sky photography to pass through unhindered. Raw images created with the colour filter set are even easier to combine into a breathtaking composite.
• For the development of the RGB filters, Astronomik measured the sensitivity curves of the CCD cameras commonly used in astrophotography in its own development laboratory in order to adapt the colour rendition and contrast of the filters to the most important sensors.
• The transmission properties and the coating technology were designed in such a way that no halos or reflections are visible. Even with bright stars in the field of view, nebulae and galaxies are imaged with the finest structures and maximum contrast.
• In addition to the RGB filters, Astronomik offers three different luminance filters. The different transmission ranges are selected so that the L filter can be chosen to match the colour correction of the telescope. This means that excellent images are possible even with moderately colour corrected optics!
• Like all filters from Astronomik, the DeepSky RGB filters have an extremely resistant and durable coating, applied to a special fine-optical substrate that is also used in space travel. The basic requirement for such material is that it is free of streaks, stresses and bubbles. Furthermore, the filter substrates are processed to the same thickness in a separate work step: Perfect homofocality and minimal wedge error are the resulting advantages!

A tip for photography under light-polluted skies: Use the Astronomik CLS-CCD filter instead of a luminance filter! You get an L-signal without the lines of sodium and mercury lamps with much less background noise.
