Gary,
"My suspicion is you might be asking too much from such a large scope"
Yes, for sure !!
In fact trying to get the maximum from my scope is really a target in itself.
With my small field of view, it is necessary to have pointing and ratio as accurates as possible to follow as perfectly as possible ISS.
You know it's like Gabriel Wiklund that is optimising again and again the autoguiding with wonderfull results at the end. Great to obtain the very best from a scope !
I want to go as deep as possible for optimising the scope. Maybe I will be blocked by mechanical problem, but at least I want to go to this point.
?
I will continue using drifting test, either by tweaking the ratio 5 by 5 as you suggest, either using the "track improvment" method but with the correction I was mentionning in my initial message for the alt correction. Even if I'm wrong with the correction I mentioned in my initial message, it will just take more iterations to achieve the best ratio I could achieve before mechanicalo limitation.
I will post the results after the iterations
Thanks for your help
Rapha?l
