Hi Brent, Suzy and all
Fact of the matter is that face-on spirals are always underwhelming from suburbia. Unfortunately, by their very nature they suffer from low surface brightness, even M83 only manages 13.3 mag/square arc second. Even in my 12", M83 is nothing but a vague fuzzy core surrounded by a faint halo of light. That pretty much describes any face-on spiral I've attempted from my outer suburban backyard.
I would go as far as to say that face-on spirals have the worst image:visual disappointment ratio of any class of DSO (unless you have real dark skies)!!!
