Thanks Greg and Tim, I was happy with the tracking of the mount but not happy with the Orion OAG. I did some tests last night at a focal length of 2500 mm and the OAG. It was really difficult to get stars to focus at that focal length and the best I could get was an unfocused blob. Anyway I went with that and did 5, 10, 20 and 40 min guiding with the naive FL of my 10" SCT.
I was able to get perfectly round stars out to 40 mins so I was happy with that. I'll post some pictures at a later date. The Orion OAG is a knock off of the Celestron OAG which is better built in my opinion but if I were to buy one now it would be on the condition that you get it to focus.
