Wow cheers for the input guys, i really appreciate it.
Thanks glend for the link to that thread it was good read and interesting to see people's point of view of mirrors used for imaging.
So really skywatcher has generally better quality build, whereas GSO is a little bit less, hence the price difference. Mirror quality is still a little bit debatable.
I don't think I can justify a cf, I'm pushing the budget (and the mrs) as it is.
I've been looking at Andrews website at the black diamond 200/1000 with the neq6pro. I was undecided on either the heq5pro or the neq6pro but from what I can gather I would be better of with the neq6pro in the long run.
Cheers again everyone for the great info! Glad I signed up to the forum
