Nikon announce the release of the new Nikon D810A, an FX-format digital SLR camera designed exclusively for full-scale astrophotography for capture of vivid reds in photos of nebulae that emit H-alpha light.
The Nikon D810A is an ultra high-definition model that boasts the best image quality in the history of Nikon digital SLR cameras with an effective pixel count of 36.3-million pixels, a Nikon FX-format CMOS sensor with no optical low-pass filter, and the latest image-processing engine, EXPEED 4. It makes the most of the incredible rendering capabilities of the D810, while utilizing an optical filter adopted to enable beautiful reproduction of vivid reds in images of nebulae that emit H-alpha light , something very difficult with run-of-the-mill digital SLR cameras. The optical filter on the front surface of the image sensor is capable of four times greater transmission of H-alpha light than is that used with the D810. This enables clear and vivid reproduction of the strong red H-alpha light emitted by nebulae and galaxies.
D810A specifications have also been modified from those of the D810 to make astrophotography easier and more enjoyable. Modifications include the addition of a long-exposure manual (M*) mode that supports exposure times up to 900 s, and a live view preview function that makes focusing and composing images easier with display of a preview at a shutter speed of 30 s when an exposure time longer than 30 s is specified.
In addition, the D810A has inherited a number of functions from the D810 that are convenient for astrophotography, including the ability to enlarge the view through the lens displayed in the camera monitor during live view up to approximately 23x to facilitate accurate focusing, an electronic front-curtain shutter that thoroughly suppresses mechanical shake, and a continuous shooting function with no limit on the number of shots possible for creating beautiful star trails (apparent motion of stars around the Earth).
What’s more, the use of genuine NIKKOR lenses with the D810A maximizes the camera’s resolving power made possible with the high effective pixel count of 36.3-million pixels for enjoyable shooting that even lovers of astronomical photos will find more satisfying.
