With my HEQ5 accurately polar aligned I was able to get almost all my
subs acceptable @60 secs, and about 50% acceptable @90 secs, and
about 20% @ 120 secs, and around 5-10% @ 150 secs in tests I did
at my scope's prime focus {1000mm].
How are you polar aligning? You need to be within a few arc seconds accuracy.
Your belt drive will pretty much eliminate PE at that point in the drive system,
but the gearbox will probably introduce it's own.
