Capture the jewels of the night sky with Nikon's first DSLR dedicated to long-exposure deep-sky astrophotography. The D810A records the brilliant red tones of H-alpha emission nebulae with advanced levels of detail and sharpness, wide dynamic range and rich tonality almost unimaginable until now. Take your passion for the cosmos out of this world with the Nikon D810A.
Based on the award-winning full-frame D810, the D810A retains all the features of its hugely successful sister camera, with the addition of capturing the brilliant red tones of H-alpha emission nebulae than your standard DSLR. Celestial objects like emission nebulae can be captured in staggering detail by the 36.3 megapixel full-frame CMOS image sensor, which has no optical low-pass filter - much like the D810 - for even greater resolution, as well as a 200-12,800 ISO capable of expanding to 51,200. Newley developed is the 656nm wavelength for enhanced sensitivity, thanks to the infrared (IR) cut filter optimized to allow transmission of the hydrogen alpha spectral line, which results in four-times sensitivity. The result is striking images of the beautiful reds of nebulae, bright constellations and the systematic star trails of the night sky.
Capture the faintest celestial objects with brilliant clarity, that would never be possible with a standard DSLR. An electronic front curtain shutter eliminates internal vibrations - key for sharp long exposure images, the Virtual Exposure Preview helps you frame and focus when in BULB or Time Mode, and the Long Exposure M Mode enables exposures up to 900 seconds (15 minutes). For added clarity, Nikon provides a free downloadable Capture NX-D software with an Astro Noise Reduction filter that eliminates pixel artifacts without sacrificing stars.
Shoot an endless number of images for epic stair trail images by slowing your shutter speed to produce beautiful light trails. Take up to 9,999 photos at any shutter speed with the Interval Timer and create smooth, even time-lapse sequences in-camera or in post production with optional third party software. Counteract the high capacity of images stored on your memory card by shooting in 12-bit uncompressed RAW size S file size without the fear of sacrificing image quality.
Aesthetically, the D810A isn't much different than its counterpart, except for a few small changes that make a world of difference. Designed to withstand the hardships of long-duration, high-volume outdoor shooting, the cameras shutter life has been tested to 200,000 cycles, and its rugged magnesium alloy body has been stringently tested to be weather and dust sealed.
