The color correction filter blocks unfocused light in the red part of the spectrum (IR) to 100% - but above all suppresses over 50% of the interfering stray light in the blue spectral range - without changing the color impression of the image. The most delicate details of lunar craters and planetary surfaces can be seen with a much higher contrast.
The color correction filter blocks defocused light in the blue spectrum, as well as in the red part of the spectrum (IR) above 700nm, usually seen in small achromat telescopes.
Correct Chromatic Aberration
Plasma-enhanced dielectric coatings result in hard, scratch-resistant and waterproof filters.
Various Application Scenarios
The smaller details on craters of the Moon and planetary surfaces are so much more visible. The NIR is fully blocked up to 1150nm. Details on planets are shown much clearer when using CCD/CMOS-cameras.
