Astronomik Deep Sky RGB 36 mm Color Filter Set


Astronomik has added to their already first-rate collection of RGB filter offerings with these Deep-Sky RGB Color Filters. Designed to supply peak deep sky imaging performance for CCD cameras, these filters will give your imaging results a boost by providing the highest quality data for incredible photos with intense colors as well as sharpness and contrast that are unsurpassed.

These Deep-Sky RGB color filters from Astronomik emerged from an long, rigorous research and development process. They are the most advanced RGB filters for Deep-Sky imaging currently available. Astronomik DRGB filters feature transmission curves made to provide distinct and brilliant colors with strong reinforcement for emission lines that are the most critical. Converting the data captured with these Deep-Sky RGB filters into a spectacular final masterpiece is simple and uncomplicated.

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.
