Hi Gavin. It looks like you have got astro fever
I can relate to seeing that first bit of Nebula on the back of the camera screen for the 1st time

Mind blowing.
Does your mount have a polar scope? I have found by doing a quick line up with the Octans in the polar scope will get you closer.
I enjoy the challenge of this hobby/lifestyle ( more the latter) and the rewards it can produce and i can relate to just going outside for a quick look and end up setting up and digging in for an imaging session

I too live in Adelaide's south and am probably not too far away if you need help with something, i'll do my best (i'm still learning too).
