Nikon D810A is the first full-frame DSLR specifically meant for astrophotography enthusiasts

Astrophotography is a genre of specialised photography which involves shooting astronomical objects such as planets, stars and so on with the skies as the background. This is meant more for aesthetic reasons than for scientific research. Nikon has released the D810A, which is a camera which will specifically cater to the astrophotography enthusiast. Priced at $3,800 (which comes to approx Rs 2,36,250), the Nikon 810A will start selling from May onwards. The Nikon D810A comes with a 36MP full-frame sensor and is essentially the **Nikon D810** , with the infrared filter or IR filter modified for astrophotography. The general camera has IR filters which are broad-ranging and filter out some visible red light as well as IR radiations. The filter on the D810A is built in a way that it is more sensitive to the long-wavelength red light than say a regular DSLR. This allows the camera to capture the Hydrogen Alpha spectral line which is the precise colour emitted by hot clouds of Hydrogen gas that are seen in emission nebulae. According to DPReview, it is most likely to give a reddish tinge to regular photography. It offers a better ISO range going from ISO 200 - 12800 (expandable to ISO 100 - 51200).  You also get a new Long Exposure Manual Mode which allows you to set shutter speeds from 4 to 900 secs (15 mins) before you switch to the Bulb mode. Just like the Nikon D810, the D810A comes with the EXPEED 4 image processing engine. The camera also features a durable magnesium alloy body that is sealed against dirt and moisture. It comes with the same 51AF points, 3.2-inch fixed LCD screen and supports full HD video shooting as well.
