I know you aren't keen on collimation but it really takes 5 minutes to get it spot on and cone be done in daylight.
If you want to give it a test run let me know.

Thanks Alex, appreciate it! :-)
I'm starting to think an 8" newt is pretty much my only serious option. I need to consider whether the extra light gathering power and colour is worth the effort over a smaller, say 120mm triplet refractor.
I think if I go with a mirror-based system I'm restricting my options to ones with a carbon tube. Is your 8" CF or steel?

Cheers Glen. Unfortunately that's way out of the equation. I'm looking to spend no more than 3k (landed) and it needs to sit on my NEQ6.

TS ONTC F4.5
