SVBONY Color Correction Filter for Lunar and Planetary Surfaces
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.
- Hight Quality Coating: Plasma-enhanced dielectric coatings result in hard, scratch-resistant and waterproof filters.
- 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.
- The smaller details on craters of the Moon and planetary surfaces are so much more visible.
- Can be used well before the focal point of the optical system, without any loss of sharpness, as a single filter in front of a binocular for a focal projection with digital cameras.
- The NIR is fully blocked up to 1150nm. Details on planets are shown much clearer when using CCD/CMOS-cameras.
