Ian,
Ok you are starting out. It needs some work.
DSLR's are not city friendly. They just don't have the dynamic range.
Go east of the Darling Ranges. Get some dark sky. Lose the LP filter. Coliminate the scope. Use in camera noise reduction. Learn how to take flats & calibrate the data. Take more time nailing the focus (2/3 out from centre field for a SCT works great). Nail the polar alignment (there is field rotation). Much longer subs to get more signal , say at least 5 minutes at ISO 400.
Stick with it. Not great yet. But has great potential.
