I'm going back east of the meridian tonight, I need some success!
This reply implies you get better results when tracking targets in the East if so then I am pretty sure it is a balance issue. I have to deliberatly unbalance my scope to be heavy in the East to prevent this behaviour, this means a rebalance after a meridian flip too, not to drastic - I have to move the CW up the shaft to the stop, quick and easy.
