I always thought that photos of other galaxies resolved into specks the size of stars in the night sky. This composite of Andromeda and the moon blew my mind: https://apod.nasa.gov/apod/ap061228.html
I think this is actually a better picture as it puts them both in the sky for a more natural comparison (to me): https://i.kinja-img.com/gawker-media/image/upload/s--Mxc-LeD...
Andromeda side to side is ~6 times the width of the moon, IIRC.
Just imagine being able to see that galaxy clearly! In fact (he says bitterly) just imagine being able to seem the damn stars any more. If you've never had a chance to see them, on a moonless night without artifical light wrecking everything, and have the chance to see infinity slowly unfold like a flower as your eyes adjust and take in more, watching the ethereal edge of the milky way appear in greater and greater detail, then you have missed one of the most beautiful sights that exist. Perhaps the most beautiful, perhaps. It really is that special.
"Wow, it's that large even though it's that far away!?"
