The Baader Planetarium UV-IR Cut Filter (50.8x3 Round Unmounted) is a must for all digital imaging with Digital Cameras, CCD Cameras and modified webcams. Also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc.).
Due to its extremely high optical quality, this filter may be stacked and used far in front of the focal plane (necessary for imaging uses). Like the Baader Planetarium Contrast-Booster, the UV-IR-Cut filter uses the very latest coating technology, to deliver the finest filtration quality.
