Here's my M27 http://astrob.in/114939/0/
I didn't spend much time processing this as my flats and biases failed. So this is a stack of just the lights. I think I'll revisit this when I sort out my calibration frame problems. I think it hints at how good the wipe module is!!!

Not too shabby for failed flats and bias! Your optical train and CCD output must be pretty good to begin with. When dithering, bias is already much reduced.
