"IC 439" is indicated near the lower left corner. Please do not waste your time trying to look for any object there:

Initial observer Max Wolf described it as "most extremely large, extremely extended", but there is nothing resembling the description anywhere near the respecting position. Obviously, this was a defect on Wolf's plate, and it is in fact a nonexistent object.
