Thanks Rick - I should never have sold that P2Z to some lucky bugger eh?
And I couldn't find anywhere that still had the non auto-guiding version, which is how I ended up speaking with Richard Taylor. He is a pretty good guy, but he must be busy or something - the only way I'd get an email reply was to ask if I could pay him money. He's happy to chat on the phone though.
I'll let you know how I go when it gets here Malcolm. Still mulling over polar alignment in the suburbs, but I have a couple of ideas to try out.
