Ready to ship today. Images of Tycho lunar crater and Saturn were taken with this filter by me. Check out my other listing's for more filters and 2x Barlow Lens'

Infrared or IR light is invisible to the human eye, so it is not a concern when you are using your telescope visually. However, when you add a camera to the mix, it's a whole other story. Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem because infrared images are blurry as they all get out. That means your nice, sharp visual light image is degraded by the addition of the infrared layer. This problem can easily be solved by blocking the infrared, and the SVBONY IR-Cut filter will do just that. This filter is a must for all digital imaging with digital cameras, CCD cameras, and modified webcams. It's also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc.). Due to their extremely high optical quality, these filters may be stacked and used far in front of the focal plane (necessary for imaging uses). The UV-IR-Cut filter uses the latest coating technology to deliver the finest filtration quality and lifetime durability. Eliminates violet halos around bright stars (more effectively than simpler Minus Violet photographic filters).
