The D810 is a very capable camera indeed, but if you are a starshooting looking for a model that can do what you ask of it, then the new Nikon D810A is the answer. There is so much more to astrophotography than just attaching a camera to a telescope, which I found out the hard way all those years ago when Mars was it its largest and brightest.
Nikon came up with the D810A for this very reason, but be warned, even though it is an updated version of the D810, you cannot really use it for normal photography because the colors will be distorted.
Looking over the Nikon D810 specs we can see that D810 owners will feel a little sick of the updates, but just remember what we said above, you cannot use this new model for your usual shots. You get a 36.1-megapixel sensor, which makes use of an electronic front curtain shutter, this is said to help reduce vibration.
Seeing as though you will be using this at night there is more chance of moisture in the air, and so its moisture-sealed magnesium alloy body helps to get around that minor issue. You get an ISO range of 200-12,800 and the ability to set your shutter speed from 4 seconds to 15 minutes.
To help improve your night-time images of the stars, Nikon has included an impressive filter called astro noise reduction.
