TS-Optics 1.25" UV & IR Cut Filter - Low Profile Filter Cell
TS-Optics 1.25" infrared blocking filter for astrophotography - moon, planets and deep-sky in a short cell.
♦ Complete blocking of the infrared light for increasing sharpness in lunar and planetary photography ♦ Blocking of UV light ♦ Almost full transmission of the visible spectrum ♦ Good protection of the camera sensor from dust particles ♦ Low-profile filter cell with only 4 mm height (without filter thread)
The filter blocks UV and infrared light. The surfaces are fine-optically polished and plane-parallel for maximum contrast. With its dielectrical coating, the filter is particularly hard-wearing and durable. The filter can be mounted even in very compact filter wheels or filter sliders, as the cell is very short with its 4 mm height.
♦ Lunar and planetary photography: Telescope optics, Barlow lenses and eyepieces are corrected for the visual spectral range, not for infrared light, but camera sensors are sensitive even in the infrared range. The result is a considerable reduction of sharpness. The TS-Optics IR1-E blocks the infrared light, the sharpness increases. ♦ Deep-sky photography - CCD astrophotography A similar effect can be noticed here. Without the IR cut filter, the stars seem to be large and a bit "softer". By blocking the IR light, the star becomes better defined and sharper. ♦ Dust protection The filter shows no effect when observing visually, as the human eye is not sensitive to infrared. Thus we alreadily have a "built-in" IR cut filter. But the filter protects the delicate accessories from dew and dust.
