I meant as images upon a ccd frame possibly having different photocentre
solutions due to marked brightness difference despite being same object,
not resolved as (a) physical entity(ies) in Space.  Though an SS Cyg
like object should be comfortably above TASS min mag at minimum, at
maximum it'd be near what appears to be the upper TASS limit, going from
the max mags I can find in CD 23.
