Antlia IR Pass 685nm 1.25" Planetary Filter (ANT-IR685-125)

Antlia IR Pass 685nm 1.25" Planetary Filter (ANT-IR685-125)The Antlia IR Pass 685nm filter is an absorptive filter that allows infrared light with wavelengths of more than 685nm to pass through. At these longer wavelengths, the sensitivity of the unaided eye is reduced, so it is not suitable for visual observations. The filter is highly recommended for any planetary photography. At long wavelength spectral range the atmospheric air turbulence (seeing) has much lower impact on the sharpness. The closer to the
