Astronomik Deep-Sky RGB Color Filter

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.

An extended, detailed resarch and development process has led Astronomik to create these new Deep-Sky RGB filters. They are the most sophisticated Deep-Sky RGB filters available for imaging at this time. These filters feature transmission curves designed to provide intense, vivid colors with firm support for emission lines that are the most important. Turning the data taken from these DRGB filters into a spectacular finished image is easy and straightforward.

Throughout the design process for their Deep-Sky RGB filters, Astronomik paid close attention to the sensitivity curves of the most popular CCD cameras currently on the market. This led to Astronomik coming up with a way to make their filter set compatible with all different types of sensors from KAF- and KAI- sensors to Sony chips. As a result, 1:1:1 ratio RGB exposures are possible with all sensors with only minimal adjustments required in order to attain ideal image colors.

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.
