Svbony SV231 Fringe Killer Color Correction Filter 1.25/2inch for Lunar and Planetary Surfaces - W9186A / W9186B

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.

Features

1.Hight Quality Coating: Plasma-enhanced dielectric coatings result in hard, scratch-resistant and waterproof filters. 
2.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.
3.The smaller details on craters of the Moon and planetary surfaces are so much more visible.
4.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.
5.The NIR is fully blocked up to 1150nm. Details on planets are shown much clearer when using CCD/CMOS-cameras.
