I have been running Tpoint and Automapper II the last 2 nights on the CDK.
Your final result there is similar to what I got tonight. Mine went as low as RMS 17 with 102 points mapped. I did several runs each time I adjusted the Polar Alignment after fitting the data and getting rid of outliers. It took 9 terms to get there. I simply used the suggest terms button and accepted it and watched the RMS number. I ran about 50 to 100 points in a run and then adjusted the PA then slewed to a bright known star, centred it, deleted the T-point model, then started a new one, then synched the star then started the new mapping run after mappung the current position (I don't think that is required for a run though).
As far as 6 points for PA I would think that is highly inadequate. Even just fitting the data and getting rid of outliers you see the suggestions for the PA adjustment change.
I have used 2 cameras now. The FLI ML8300 which is similar to your camera and the PL16803. The ML8300 I used 10 second exposures at 2x2. I added the USNO catalague from Marcus to my database in the Sky.
With the PL16803 I use 3x3 and 10 second exposures and it works well and usually gets more stars. Both are fast as the FLI's have super fast downloads of 1 sec or less. So total time is about 19 seconds per mapping including slewing time. So a 100 point model only take 40 minutes or less.
I found I had to take an image in CCDsoft then insert WCS research and it plate solves and gives the north angle. I then added that into the automapper default settings. Then it plate solved. It would fail without that north angle. Its done that twice now where it would not get the north angle when you press the get button next to north angle. So if you are not doing that try getting it through CCDSoft. I take it you have CCDsoft server settings turned on per the manual.
The only failures I got were because of cloud. Its probably a bit harder to do with a full moon. Perhaps that was all it was.
I have done 3 iterations in 2 nights and tweaked the polar alignment each time. Make sure you are turning the dec knob the right way.
I also check how its going by doing a bit of autoguiding and watching the errors and seeing if they are in fact lower than before. They have been so far.
