Hi Matt,
If you were after a good site down the Peninsula way, you could join the mornington peninsula astro society you then have access to the Briars.

a 5x powermate will up the scale of the planets.
You seem like a bit of a perfectionist Matt and I wouldn't normally point this out to someone after their first astro shot!! But you're quite advanced already so i'll give you some feedback on orion - i hope it doesn't come across as harsh but just trying to be helpful.
There is coma around the fringes so a coma corrector should be on your list (that's just a function of your setup not your capture). I'd also say the focus is off a fraction off and either the tracking appears to be a tad off (or it was perhaps windy) and/or the scope needs some tighter collimation.
But as i said earlier stellar effort for a first shot! Mine definitely wouldn't compare.
Looking forward to more.
Cheers
Rusty
ps in the meantime you could possibly play around with lens correction to offset the coma a bit - if you use photoshop.
