On the matter of resolution, I'm sure you are right. I recently changed from 1"/px to 0.65"/px, and it shows at my Mt Macedon site which never gets much better than 1.7" seeing...
I'm very jealous of you getting so many hours of sky time - recently I've been lucky if I can two decent nights with good seeing in one dark period

Cheers Mark, always wanted to do a good deep M83, I originally wanted more exposure but after three months of slow collection, I was impatient to see what I had and started processing and woah! I was gob smacked...so, meah, just kept going and all the aspects I was hoping for were revealed, without all the extra exposure that I had imagined would be necessary, the blessing of transparent dark skies I guess?
Since starting digital imaging back in 2003, I have done serious imaging (and visual observing), from various spots around Canberra, Maitland, Newcastle, Kurri Kurri and from Wiruna (ASNSW premier dark sky site) and Eagleview edges out or completely floors all of these places, in all aspects, seeing, darkness and transparency, its great
So I am not surprised your drop from 1"/pix to 0.65"/pix is returning dividends for you from Macedon. All my gear was extensively utilized for nearly 8 years, at my old observatory at Wallaroo, on the outskirts of Canberra and then simply moved 60km south and 850m higher into the Tinderry's and the improvement has been mind boggling, in every session, both visual and imaging
So yes, I am sure dropping my image scale finer will be worth it.
You can see my conditions quantified and some comparisons between Wallaroo and Eagleview
HERE, it's no fishing story, I'm not making it up
