Antlia IR Pass 850nm 1.25" Planetary Filter (ANT-IR850-125)

Antlia IR Pass 850nm 1.25" Planetary Filter (ANT-IR850-125)The Antlia IR Pass 850nm filter is an absorptive filter that allows infrared light with wavelengths of more than 850nm to pass through. It is a supplement filter of IR Pass 685nm. 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
