Yes as we all know , the mating element makes or breaks an objective and FPL51 and Lanthium are well regarded in this respect and with SW's track record ( ED80 -100 and 120 , yes I know these are SPL53 but not a Lanthium mating element ) I believe these should be a little better than the APM/Lunt 150mm APO's .
Computer mapping has come a long way in the 5 or so years since APM did the un-believable by allowing us with little money the chance to own a 6 inch APO .
Well done Sky Watcher
, I will be following these very closely ( along with plenty of others I am sure
) .
Go on Lewis be out beta tester here in Australia .
. Go on !
