The Astronomik Deep-Sky RGB 31mm filters are the result of a long and detailed process of research and development. We have created the 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 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 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 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 nebulas or galaxies
Additional to the Deep-Sky RGB 31mm filters Astronomik now offers you three different Luminance filters. The different spectral window of each 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 Deep-Sky RGB 31mm filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striae or internal strains. All substrates are made to exactly the same thickness, so all of our filters are parfocal.
