Technically the two galactic clouds are already touching, according to some paper I read a couple years ago

Oh, wow. I expected someone to correct me and say it will be much sooner due to the size of the two galaxies but didn't think I was that far off.

Extremely technical use of "technically" - we're talking about maybe 1 atom of hydrogen per cubic meter, but if that atom is bound by a galaxy's gravity it sort of is part of that galaxy, kinda.

So it's coming at us at 0,1% the speed of light?

We're gonna need a crew of oil rig workers to divert it.

This was on a canon 90d on a star adventurer 2i, with a 50mm f1.8 lens stopped to around f5.6
30sec exposures at iso 800 stacked up using Siril
