Player One IR850 1.25" 850nm IR Filter S-series Infrared Filter for Venus Lunar & Planetary Imaging
Description:
The IR pass filter is developed using a process adopted by large factories. It uses high-quality optical glass substrate and multi-layer composite coating process, so it has an excellent optical performance in astrophotography.
The 1.25" IR850 NIR filter is a pure IR filter. This filter can be used to collect the infrared band. For Venus photography, the IR850 can collect rare images of clouds in the infrared band of Venus. Used with a UV filter, the IR filter can be used to take pictures of the UV clouds, enabling you to create beautiful photos of the clouds of Venus. It can also be used to take near-infrared images of the moon and planets. The IR850nm near-infrared filter is more of a mysterious term than other filters.
