TRANSMISSION OF THE H-ALPHA SPECTRAL LINE OF THE OPTICAL FILTER (IR CUT FILTER) HAS BEEN INCREASED BY APPROX. FOUR TIMES
For the D810A, transmission characteristics of the optical filter placed in front of the image sensor have been reassessed for astrophotography. With a general digital SLR camera, transmission of reddish light in the visible light range is restricted to reproduce the colors of subjects properly. Because the H-alpha spectral line (wavelength: 656.28 nm) is located within this range, nebulae that emit with the H-alpha wavelength can be captured only palely. On the contrary, the optical filter of the D810A achieves high transmission of reddish light in the visible light range, quite close to the infrared range. As a result, transmission of the H-alpha spectral line has been increased by approx. four times, compared to the D810, achieving the reproduction of nebulae that emit with the H-alpha wavelength beautifully in red as astrophotographers expect.
Note: When you shoot photos using light sources that have a significant amount of near-infrared wavelengths or general subjects that feature high reflectance at near-infrared wavelengths using the D810A, the resulting image may be much more reddish than the actual color. Because appropriate color reproduction cannot be obtained, this model is not recommended for general photography.
