Please note: Only one filter is included in the scope of delivery, not the complete RGB filter set!
The new Astronomik Deep-Sky RGB filter set is specially designed to meet 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 important in deep sky photography to pass unhindered. Raw images produced with the colour filter set can be combined even more easily to create a breathtaking composite.
- To develop the RGB filters, Astronomik measured the sensitivity curves of CCD cameras commonly used in astrophotography in its own development laboratory in order to adapt the colour reproduction and contrast of the filters to the most important sensors.
- The transmission properties and coating technology have been designed so that no halos or reflections are visible. Even with bright stars in the field of view, nebulae and galaxies are reproduced with the finest structures and highest contrast.
- Astronomik offers three different luminance filters to complement the RGB 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 even with moderately colour-corrected optics, excellent images are possible!
- Like all filters from Astronomik, the DeepSky RGB filters have an extremely resistant and durable coating applied to a special fine-optical substrate, as used in space flight. The basic requirements for such material are freedom from streaks, tension and bubbles. Furthermore, the filter carriers are processed to the same thickness in a separate work step: Perfect homofocality and minimal keystone distortion are the resulting advantages!
A tip for photography under light-polluted skies: Use the Astronomik CLS CCD filter instead of a luminance filter! You will get an L signal without the lines from sodium and mercury lamps and with much less background noise.
