The object cloud depends on size, and size distribution. This could
involve anything from micron to meter size, and even larger.
We can't predict the distribution spectrum of the objects,
unfortunately.

I think it will look a lot like a very dusty star.

This assumes you can actually watch the construction work. On one
hand, it's unlikely, since such things are extremely long-lived objects,
on the other hand you'll never observe a mature object because the
expansion front would have long sweeped through your own system,
restructuring it (and thus eliminating (emergence of) observers).
