Two galaxies in one image how do we mark?
Have extremely feint galaxy in centre. but quite clear side on galaxy on the left. How would we catalouge this?

First of, always classify the object in the center of the image (even if it is the most boring one !).
Here , it's the blue smudge : a very faint and fuzzy galaxy. I'd go for irregular.
The galaxy to the left is an edge spiral or disk.
Happy Hunting ! 😄
