Astronomik Deep Sky RGB 2" Color Filter Set


Astronomik welcomes a new line of RGB filters to their already first-rate filter offerings. Designed to provide maximum deep sky imaging performance with CCD cameras, these Red, Green, and Blue Deep-Sky filters enhance your imaging results by delivering superior quality data for extraordinary images that are without peer in terms of sharpness, contrast, and vivid colors.

Resulting from a long and complicated research and development process, these new Astronomik Deep-Sky RGB filters are the most advanced RGB filters for Deep-Sky imaging available today. Transmission curves on these filters are designed to provide clear, intense colors with a strong support of the most critical emission lines. Processing the data taken from these filters into a stunning final masterpiece is more straightforward.

During the design of the Deep-Sky RGB filters, Astronomik took a close look at the sensitivity curves of today’s popular CCD cameras. The result was that they 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 colors in your image!

The transmission curve characteristics and coatings on the new 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.

Like all Astronomik Filters, these 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 striae or internal strains. All substrates are made to exactly the same thickness, so all of our filters are parfocal.
