Nikon D810 DSLR
the D810a, Nikon has finally come out with a true astrophotographic DSLR camera with a modified long-wavelength filter that passes more of the hydrogen-alpha wavelength at 656.28 nanometers in the deep red portion of the visible spectrum. The high image quality of the D810a comes from the excellent low-noise performance of its sensor. The camera's excellent high-ISO performance will benefit starscape, panorama, and time-lapse photographers who will really appreciate its built-in intervalometer, time-lapse function that creates movies, electronic front curtain shutter, and virtual horizon.
