I have to concur with Fred on the point of QE. I can do things with the ST-10 that frankly you can't with the QHY, merely because of sensitivity.

On the subject of oversampling, I'm yet to be convinced that it's a bad thing, I suppose I'm spoilt as I have the QE, but I find that I can tell the difference in resolution between binned and unbinned images.

For instance have a look at two subs from the recent NGC 2070 images I have done. One is Ha unbinned, the other is red and binned 2x2.

I can definitely see that the binned image stars are blocky.
