For only 13 seconds that’s pretty remarkable. I have to wonder what you could do with a tracking mount and stacking?

It's my wife's birthday shortly so I may never find out.  Every time I save up enough for a quality EQ Mount, either one of my cats needs an emergency visit to the vet or my garage door breaks down etc.  I'm actually curious to see how much more detail and faint nebulous material might be revealed with a tracked shot using this lens + a lower ISO and a smaller aperture.  15 seconds produced star streaks but 13 seconds made for a decent compromise. 10 seconds was better but required ISO changes to get a similar exposure.

I took some shots of the Galactic Core with the EOS 6D (Full Frame) + EF 24mm f/1.4L II USM lens with 20 second exposures at f/2... and there was still quite a lot of Coma visible.  Which is something else I can appreciate from the 32mm.  It has very little Coma. The difference between these two lenses in that respect, even at f/1.4, is surprising.
