2. Upper limit for guiding exposure for maximum expected PEC/guiding excursion (again, likely to only be an issue for cheaper mounts with greater worm/PE concerns).
Rob,
Not exactly what you were asking about , but related. The polar alignment report in the Tpoint add on to TSX has the following recommendations based on your Tpoint model. Mine is attached bellow for my polar alignment model...
