To get them out, I don’t know…but to keep them out, most homes in my area put plastic or metal cages over them. I never had birds get into mine since they prefer the two story homes around my single story, but I put plastic cages on mine as a preventative measure. I got them at the local Lowes.

I don’t know if it still exists or not, but there was old open-source planetarium software, called Celestia I believe, that let you play around with this. For example, on a planet around Alpha Centauri, the Sun would appear as a sixth bright star in Cassiopeia, making the “W” look more like a zig-zag.
