Gary,
Again - thanks for your insight. Yes my sampling was only in one quadrant South East to North East, reading Tpoints documentation that was the way I thought you were supposed to start off!
MaxPoint was equally distributed over half the sky on my last run (see below).
Next steps - when the clouds finally clear:
1. Ray Gralack suggested I re-run PEMPro - just to see if the pier has settled since my last run - happy to do that.
2. I understand the need for a realistic sample size - I think I'll shoot for something with several hundred data points. I have the full pintpoint and AutoMapper and MaximDL (but not CCDSoft v5) - so I might as well put that what I have to automated used and try an automated sky map with plate solves to build a more realistic model.
MaxPoint states that the circles it places around stars are at 1 and 3 sigmas and the numbers are the diameters of these circles - not the radius. That's why I read MaxPoint saying I had a radius of +/- 16 arc seconds for 1 sigma. So given Tpoint's circle said 20.3 arc seconds - I presumed that was the diameter of the circle - not the radius - I didn't image it would be twice as bad as MaxPoint's model.
3. Once I have MaxPoint auto calibration done I'll post results, then I'll try AAG_Tpoint mapper (which works with SKy 6 PE and MaximDL) and see what result it gives me with a similar sized data set.
Challenging to nail down that final bit of polar alignment - when you want to go do very low arc minutes of even a few tens of arc seconds. Hope it doesn't sent me crazy!
Thanks,
Matthew
