I know you shoot some great stuff Peter, but this image was produced with a Nikon D7000 (same chip as my D5100):

I would be over the moon (so to speak) if I could take an image as good as that with ANY sensor money can buy.

Once you know what to look for these artifacts are a bit like a dunny in a desert.
QE and noise are however are the big killers. When you push the envelope...ie Narrow-band sub-frames of 30-40 minutes..DSLR's simply don't cut it....and it is here, that cooled CCD's become objects of wonder. |
