Product description

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 infrared band, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing), resulting  in the sharpest and highest contrast image possible.

It also possible to image the other planets during daylight due to the dark background sky created by the 685nm IR Pass Filter.

Erityisen hyvä

Erittäin hyvä ja siisti pakkaus. Itse suodinta en ole vielä päässyt kokeilemaan, on aina satanut.
