Well two side by side scopes - one says the star is not drift - the other says it is. Focus looks pretty good on both - so I wonder what can cause the pointing error if its not a small - say 7 arc minute mirror shift?
The fact two side by side scopes reported different results under full automate drift aligning - and believing the small scope produced such dramatic benefits for both scopes makes me think it has to be the mechanical flexure in the larger scopes optics causing this error.
