Two weeks ago I purchased a new NIKON D7000. A wonderful camera ! Here are just two of a bunch of Nightsky images I made just for tesing the camera. No correction exept some sharpening has been applied. There was no camara internal noise reduction. Looking into the full size images, there are just a few hot pixel visible. Great stuff !!
Nikon D7000 - 18mm f3.5 - ISO1600 - 30sec - No camera noise reduction !
Nikon D7000 - 135mm f2.8 - ISO1600 - 30sec - No camera noise reduction !
Same image as above, but 1:1 crop. The blurry startrail is M57 ! Was a little bit wrong in the original above.
