Description

I normally shy away from these widefields with galaxies since the galaxy itself seems so small, but there is a certain perspective of vastness that is lost when the galaxy fills the frame. This is still "zoomed in" here to some extent (320mm), but kind of puts a huge galaxy, once thought to be the entire universe, in perspective.
