Very nice photos, as usual, Marco. It is interesting to see how much the stars smear over such a short exposure. Reminds me of just how fast we are all moving. Is the smearing reduced much if you shoot the sky closer to the horizon or does that just increase the exposure time and give you the same results?

There's no smearing on the stars in the 22mm shots.  There's a minor amount of coma towards the edges which is fairly well controlled for the apertures used.  But on the super-sharp 11-22mm lens @ f/4, the nebulous areas of the Milky Way are soft and many of the dimmer stars are not visible due to their rendering scales per-pixel.  I noticed this before when using this lens on the original EOSM to shoot the Milky Way a couple of years ago (see images below).  Note that these images have been enhanced during processing to lighten the brighter spots of the Milky Way.  The unedited JPEGs were underwhelming.
