Hi Mike, wow - bang on the money there. Your image is exactly the same as mine
The smearing effect is very evident! The confusing thing for me is the fact that there is a distinct pattern to it, it's almost as if the background noise is tracing out the same star-trail pattern when you take a long exposure and see stars rotating around the SCP.
The problem is then compounded by the fact that the stars and DSO are all tight/compact objects with no obvious rotation
Were you ever able to replicate the result? I could just bin the images I took on the night, but it seems such a waste of 2+ hours of data on M83.
One thing I do remember doing differently that night was I changed my DSLR colour balance from daylight to fluorescent. I don't see how that would make any difference though.
Cheers, Evan
