Come to think of it I’ve never heard or seen anyone getting down to 0.2 arc sec error for guiding, even OAG,s on amateur equipment
That’s almost absolute perfection in sync with earths rotation at round the pole inclusive of atmospheric disturbances and optical / chromatic aberrations etc...
Has anyone else heard or seen or produced those astonishing guiding numbers from basic amateur equipment ??
