Astronomik Deep-Sky RGB Key features:
- maximum transmission of up to 95%
- Ultra-Sharp, pinpoint star images
- High contrast
- easy to process data for vivid colours in the final image
- optimized spectral windows for max photon counts on the sensor
- made on finest, opticaly polished glass
- extremly durable, scratch resistant coating
- MFR Coating technique for a wide range of focal ratios
The new Astronomik Deep-Sky RGB filters are the result of a long and detailed process of research and development. Astronomik have created their most advanced set of RGB filters for Deep-Sky imaging available today.
The transmission curves of the three filters are designed to give you strong and vivid colours with a strong reinforcement of the most important emission lines. Data taken with the new Astronomik Deep-Sky RGB filters is easier to process into a beautiful final masterpiece.
Feedback from our test-users and the first customers is really exciting. All of them reported smaller, sharper stars and this was one of our design goals, so these filters are designed to give you the best contrast and the smallest stars possible!
During the design of the Astronomik Deep-Sky RGB filters we took a close look at the sensitivity curves of today’s popular CCD cameras. The result was we found a way to make one set of filters for all kind of sensors ranging from KAF- and KAI-sensors, to the chips made by Sony, meaning you can do 1:1:1 ratio RGB exposures with all sensors, with only minimal tweaking necessary during processing to achieve perfect colours in your image!
The transmission curve characteristics and coatings on the new Astronomik Deep-Sky RGB filters have been designed and engineered in such a way that no halos or reflections will be visible. Even with bright stars in the field of view you will be able to reveal the faintest structures in nebulae or galaxies
Additional to the Deep-Sky RGB filters Astronomik now offers you three different Luminance filters. The different spectral window of each new Luminance filters is designed to tune your setup to get the sharpest image from any optical design and any camera, even with instruments with less-than-perfect colour correction.
Like all Astronomik Filters, the new Deep-Sky RGB filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striations or internal strains. All substrates are made to exactly the same thickness, so all of our filters are parfocal.
Additional note for observers working under light polluted skies:
If your observing site suffers from light pollution you should try to use our CLS-CCD as a replacement for the Luminance filter. The transmission curve of the CLS-CCD will give you approximately the same amount of energy in all three colour channels while blocking nearly all unwanted artifical light pollution. Customers who replaced the Lx filter with the CLS-CCD are amazed by the increased quality of their data. This small change gives you the opportunity to take much deeper images from your current observing site.
The Astronomik Deep-Sky RGB filters are available as single filters too. Please contact us for ordering, as they are not listed on the website.
