1.25inch IR685nm pass filter（Seeing improving filter）

Many
years ago, Moon Prince introduced the IR685 infrared filter, which only
allows red and infrared light with wavelengths greater than 685nm to
pass through, greatly improving seeing condition (because atmospheric
jitters have less impact on longer wavelengths of light). Since then, IR685 has become a great accessory for Lunar photography. This
IR685 filter are not the same as old IR685 filters. Our IR685 using
double-sided multi-layer composite coating upgrade IR685, will become
your new magic weapon!

Not only does IR685 improve seeing, but it also helps enthusiasts around the world to capture Uranus’s distinctive cloud bands.
