Please read my reply to Luc Leblanc on the BB.
you can find this at:
Because Delfi has no active attitude control system, polarization might change.
Switching polarization might help, but I understand this is not
possible for you.
You could try to figure out which passes work best for you.
Reports are appreciated!
