Actually it's not resampled. The SkyNyx 2.1M has a 1392 X 1040 pixel chip size (and 4.65 um pixels if I remember). I usually just cut out the edges where stacking shifted frames gives a fuzzy edge, but otherwise I don't resample the SkyNyx images. I haven't had good enough seeing to really push the camera. The seeing on the night was averagey, hence the poor image.
