thanks all for comments. Have just came back from lunch and tried focusing the webcam in prime focus setup. Like last night, the lens of the webcam came out, the 1.25" adapter went in. In this setup, i can focus well on land based objects up to say 100m away. Past that, i have to take the 1.25" to 2" adapter in the focuser off and push the webcam into the 2" hole and then i can get focus on land based objects say around 10km away.
As you can see by the infamous "one night in mars" video i shot, i am at the minimum travel of the focuser late in the video, but still not at focus.
here is my attempt without the 1.25" to 2" adapter in the focuser and the webcam shoved in the 2" hole by hand

I still have a bit of room to play with as i came back from minimum travel to focus. But still the ccd of the webcam is closer to secondary mirror than wih the adapters in and at mimimum travel
At a bit of a loss. I have noticed that in daylight, the mirrors are perfectly lined up, so will have ot do a collimation next week.
Off to melbourne tomorrow morning to get pissed and fall over. But taking my Dell laptop to keep up with all the news
