Here I reduced by typical ISO value from ISO1600 to ISO800. Furthermore it was the first cold night (approx. 0°C). So the noise of the DSLR is much lower with respect to my summer exposured. However, guiding was not working properly (I have no idea why!!!). RMS Error was on the order of 1.5 arcsec. I am happy with the result but as usually ... it could be sharper!
