- Designed for CCD astrophotography, the set includes Luminance-IR, Red, Green, and Blue dichroic CCD filters.
- The filters are resistant to humidity and scratching and set into a durable aluminium alloy threaded mounting ring.
- The red green and blue filters have been developed to closely match the natural colours of stars, planets and emission nebulae, whilst the luminance filter removes damaging haze and ultraviolet.
- The filters offer light transmission of nearly 100%. Please note the red, green and blue filters are not IR coated.
