Lovely Brett...
I'm working on some data I acquired on the Prawn in June at the moment... I got less than half the expsoure time that you've achieved, however our fields of view are fairly similar.
Here's a similar crop from mine (albeit, much lower resolution as my sensor has bigger pixels and my scope is half the size of yours
)
Good to see there's another astrophotographer close by... I'm in Caboolture
