hi grant,
hey were you up at linden observatory a while back?
anyhow I cant answer your goto problems but as for EPs... well you have a 6mm (generally you are going to need good seeing for this EP, and a 30mm which should give you nice wide views. so how about a 20mm and a 10 or 9mm. the rest depends on your budget. if its low you cant go past GSO plossls. bintel and andrews communications sell these for good prices.

welcome aboard!
