hi Scooter,
If you were observing from your home in Bris, at 01:00 M83 was at about 48° altitude... and from what I can see you are in in a rather light polluted area there, which makes finding a low-surface brightness object like M83 not so easy, not even in a 12" scope...
While you should be able to see its bright core now following Graham's map, I would suggest you wait until it gets a bit higher up in the sky, say 70° or higher - either between 3 and 4 AM, or from April onwards in the evening
