The Astronomik Deep-Sky RGB Filter Set is designed for use with monochrome astro cameras equipped with CMOS or CCD sensors. It allows for almost unparalleled image sharpness, contrast, and vibrant colors, especially when photographing deep-sky objects. Alongside the filter set, we particularly recommend the new Astronomik L-1, L-2, or L-3 blocking filters.
When designing the filter set, the main focus was on ensuring that its transmission curve aligns as closely as possible with modern sensors and the most important emission wavelengths, resulting in exceptionally good contrast and signal-to-noise ratio. A key consideration was to keep the size of stars as small as possible, enhancing the aesthetic quality of the image.
Like other Astronomik filters, the Deep-Sky RGB filter set is made from particularly durable and scratch-resistant glass, free from stresses and characterized by the most precisely crafted surface.
