The Astronomik Deep-Sky RGB filter set is designed for use with monochrome astro cameras equipped with CMOS or CCD sensors. It delivers exceptional image sharpness, contrast and vivid colours, especially when imaging deep-sky objects. Astronomik L-1, L-2 or L-3 UV/IR filters are particularly recommended for use with this filter set.
The primary focus during the development of this filter set was to ensure that the transmission curves are optimally matched to modern sensors and the most important emission wavelengths. Another key consideration was keeping star sizes as small as possible, further enhancing the aesthetic quality of the image. As a result, astrophotos taken with this filter set can achieve outstanding contrast and signal-to-noise ratio.
Like other Astronomik filters, the Deep-Sky RGB filters are made from particularly scratch-resistant, stress-free glass, with surfaces finished to the highest possible precision.
Key features of the Astronomik Deep-Sky RGB filter set:
- maximum transmission: 95%
- UV/IR-blocking coating
- outstanding contrast, pinpoint stars and excellent signal-to-noise ratio
- colour-accurate raw data that is easy to process
- precision optical glass of excellent quality
- particularly scratch-resistant surface
- MFR coating for use across a wide focal ratio range
