What are the red-ish smudges/blobs?
Not quite sure if I am looking at galaxies or stars, but they have this red-ish smudges in front of it. What are they?

Hello and welcome @johnson_lin 😃
They are stars - the red-ish smudges are artifacts 😃
As we are trying to image/classify galaxies that are so much further away, the foreground stars tend to cause a problem- they get over exposed, and cause weird artifacts.
