I will admit I don't know much about the geometry of our galaxy, but I
was under the impression that the disk is hundreds of billions of light
years "thick", it's just that it's quadrillions of light years across as
well. The point being, the disk is many million stars thick, and so we
should see them in just about every direction we look.

So... about 36 seconds of arc. Man, that's pretty small.
