David and I had another go last night with the 350D and Canon 70-200 f/2.8L combo, had to dodge the clouds now and again but we managed to get some images.

EQ6 tracked but not guided
Thanks for the comments, I've really only had a couple of goes of imaging so I hope to improve with time/practice. David has been having to lug his EQ6 around on the weekends but not any more, since I bought my own last week.
At the end of the 2nd image run I set the exposure to 300sec in ImagesPlus just for a hoot, it surprised me a little as the tracking wasn't too bad, I could notice some slight error in the image. Must get a guide camera, especially with longer focal length shots.
Well, I did discover its less of an issue than it seems taking the Eq6 over. Surprising how easily and quickly it dismantles and fits into the car. Setting up is pretty good too - we were all set up (laptops and all including polar alignment in under an hour. Should be quicker now though.
Still, Im sure Michael's pretty happy with his Eq6 (good excuse Mike). Its a pretty mean tracker thats for sure.
The idea of checking lat and longitude from google earth is a good one too Michael. Will have to do a more accurate check here for the Curtin Reserve.
