Player One filters employ a high quality optical glass substrate and multi-layer composite coating technology for excellent optical performance in astrophotography.
The main function of the UV IR cut filter is to correct the color balance of the image
Color cameras like MARS-C are very sensitive to both IR and UV rays, so if you want to take a picture of the planet and the moon, you need to use a UV IR cut filter to block both IR and UV rays.
When shooting the sun, strong infrared light also affects the sharpness and contrast of the image, so it is recommended to install a UV IR cut filter.
