ZWO Infrared IR Cut-Off Filter (31.7mm, 1.25") Phoenix Filter Wheel 5×2″ 85%+ transmission within the passbandThe ZWO IR Cut Filter is designed to block unwanted infrared and ultraviolet wavelengths, allowing only visible light to reach the camera sensor. This improves image sharpness, colour accuracy and overall image quality when used with colour CMOS and CCD astronomy cameras. Many astronomy cameras are sensitive to infrared light, which can reduce image sharpness because most telescope optics are optimised for the visible spectrum. By removing IR and UV
