Capture the jewels of the night sky like never before with Nikon's first DSLR dedicated to long-exposure deep-sky astrophotography. Based on the award-winning full-frame D810, the D810A records the brilliant red tones of H-alpha emission nebulae with a level of detail and sharpness, wide dynamic range and rich tonality almost unimaginable until now. Reveal the faintest celestial objects with exposures up to 15 minutes long; and noise-free performance at ISO levels as high as 12,800 (expandable to 51,000). Create star trail images that span the entire sky with unlimited continuous JPEG shooting. Whether using a fixed tripod, equatorial mount, connected to a telescope or tethered to a laptop, the D810A can take your passion for the cosmos out of this world.
