Optolong IR Pass 685nm Filter - 1.25”The Optolong IR Pass 685nm Filter blocks wavelengths below 670nm to enhance contrast and surface detail and reduce the effects of seeing when used in IR-LRGB imaging of the moon and planets. Atmospheric seeing and distortion diminish as you move further away from visible light into the infrared, and since CCD and CMOS sensors are sensitive to IR light, imaging in the infrared will improve your results. |

Optolong Clear Sky Clip Filter for Nikon-Z CamerasThe Optolong Clear Sky Nikon Z Clip-In Filter is designed to provide a very gentle filtering profile that blocks sodium and mercury lamp wavelengths (commonly emitted by street lamps). This filter shines the brightest in Milky Way photography setups and under skies that are 4 or lower on the Bortle light pollution scale. It can also shoot city night scenes. |
