Evening all,
Thanks again for all the advice. I have some time off coming up, so will try that "Solar noon" alignment trick, Martin. I can't make anything too permanent in the concrete but I think discrete drill holes or globs of spray paint might be OK...
I think it might be prudent to move the conversation across to my 'Kstars' thread here:

I don't want to incur the wrath of any admins. :-O
Cheers,
V
