my PA could probably use a touchup since i do sometimes see large star displacements when PhD starts back up - i also pause guiding during focus, also because i have an OAG. and since so far i've insisted upon focusing thru my narrowband filters, an autofocus run can take 10 minutes sometimes.
however, almost every time PhD finds the guidestar again and recenters it. i'm thinking that if you increased the size of the search box in PhD that you might be able to recover from this situation?
