Which structure is represented in this video (if any)?
I think it is supposed to be a representation of the Centaurus A/M83 Galaxy group.

These are a bunch of galaxies between 12 million and 15 million light years away.

The big central dust lane in Cen A is very recognisable.

I guess the sequence then continues through the Virgo cluster and supercluster which are roughly in the same direction.
