I just got a weird idea. Please be warned it just popped into my head so feel free to debunk it with FACTS.
what if a short distance away (less than 1000 ly) there is a layer in the milky way galaxy that contains a lot of gas and forms an ellipse following
the shape of the milky way. It would look like images were coming from a different place than they actually were due to the angle of the gas layer and
the index of refraction of the gas. Kind of like when you stick a pencil in water and the pencil looks broken. so where we think a star is is not its
actual location. This might also contribute to the blur of images from stars far away.
