Anyway, some analysis has been done on the Nikon D7000, and it looks great. Check this post on the DPREVIEW.COM forums which shows a comparison between the D7000's image processing algorithm and the algorithm used in other Nikon models prior to the D7000. It shows that the 'star eater" phenomenon is no longer an issue! The simulated star in the image remains intact, whereas in the previous algorithm sample image it does not. This bodes very well for those folks interested in using this camera for astrophotography. I am already very impressed with the quality of the astronomical images I have taken using this camera, and now have a little extra confidence that I am not losing any real detail.
To see what I have been able to achieve using the D7000, look here.
