New rumors suggest that Nikon will announce a special version of the D810 for astrophotography in the next couple of days.
If this turns out to be true, expect a similar setup to Canon’s 60Da, which features a modified infrared filter and a low-noise sensor with heightened hydrogen-alpha sensitivity and allows the camera to better capture red hydrogen emission nebulae and other cosmic phenomena.

The new 300mm f/4 VR lens is expected to be lighter than the current lens. It will feature a minimum focusing distance of 1.4m/55″ and a 77mm filter size.
