About Optolong 1.25'' IR Pass 685 nm Planetary Filter [OPTO-IRPASS]
Optolong: IR Pass 685nm filter is designed to block wavelengths below 670nm and can be used in IR-LRGB imaging to produce a sharper luminance image for the best planetary contrast as atmospheric seeing and distortion is much reduced at longer IR wavelengths.The sensor of CCD or CMOS cameras is capable of detecting light in the 350-1100nm range including infrared wavelengths. Thus RGB planetary images taken with IR as the luminance channel have visible-enhanced contrast and surface detail than standard LRGB images.
