Astronomik Deep Sky RGB 50 mm Color Filter Set


Adding to their already superb filter collection, Astronomik has introduced a new line of RGB filters. Developed to enable maximum deep sky imaging performance for CCD cameras, you'll experience a vast improvement in your end results. This is due to the high quality of data supplied by these Astronomik Deep-Sky RGB filters that translates into exceptional final images with vivid color that offer exceptional sharpness and contrast.

Astronomik's new Deep-Sky RGB filters are the result of a research and development process that has been long and detailed. These filters represent the most sophisticated RGB filter set for Deep-Sky imaging currently available. Astronomik DRGB filters have transmission curves designed to deliver distinct and vivid colors with a powerful reinforcement of the most vital emission lines. Data captured with these Deep-Sky RGB filters is easier to process into a stunning final imaging achievement.

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.
