Nikon has announced a very interesting camera specifically for astrophotography \u2013 Nikon D810a<\/a>. It has everything of the D810<\/a>, as well as an additional 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. There are a number of new features added to the D810A to make astrophotography easier and more enjoyable. New features 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. 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).<\/h4>\n
