Description:

The Player One S-Series 1.25 inch IR685nm Pass Filter utilizes high-quality optical glass substrate and multi-layer composite coating technology, ensuring excellent optical performance for astrophotography.

The IR685nm pass filter, also known as a 'Seeing improving filter,' is designed to enhance seeing conditions for astrophotography. By allowing only red and infrared light with wavelengths greater than 685nm to pass through, it reduces the impact of atmospheric jitters on longer wavelengths of light, resulting in improved image stability. The IR685 filter has been widely recognized as a great accessory for lunar photography. This upgraded version of the IR685 filter features double-sided multi-layer composite coating, making it a new magic weapon for astrophotography enthusiasts.

In addition to improving seeing conditions, the IR685 filter also aids in capturing the distinctive cloud bands of Uranus, offering unique imaging possibilities.

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!
