Your problem is that the Canon probably would be better for milky-way pictures (although with a tracker, hmm...)

I wonder how Sigma handles long expsures? I am curious. Any heat issues or anything?

But the Sigma would be better for landscape, by far.

No it would not. It would have one possible advantage of maybe slightly higher resolution - with aliasing as drawback. Apart from that it is hard to see why it would be better and the colours can be a big issue.

Consider buying the Canon for astro work, then a Sigma DP-1M, possibly also a DP-2M for landscapes.

Or maybe Sony A7r or Nikon D800 for both astro and landscape?

Then you could also try the DP-1M on the tracking mount and see how it fares.
