Fantastic image Greg! Uber luminance with low RGB exposure, still you've manage the colour noise very well. The warm glow from the nucleus has produce a very aesthetic result. Good work!
I wouldn't bother trying to compare your output with Martin's. Yes similar kit and as you mentioned Martin's processing skills greatly influence the result, but if there's a key distinguishing factor its the location which generates quality data. I seriously doubt there's a location in Australia that can compare with the consistent low seeing at sierra-remote. I just had a quick look at their meteorological data for the past 12hrs and average seeing over that period was 1.13 FWHM! And this is not a freak event, its routinely that good each night. At 4,610 ft above sea level, this is exactly what I'd be expecting! In any case, yes, get that 17" scope out of the burbs to your dark sky location. You've got a better chance of obtaining quality data in doing so.
Really hope to see more from your 17" set up. Are you controlling everything remote at your dark sky site yet? Perhaps its time, so you can really give your gear a workout even when you're not there.
