Thanks heaps Julian
This was of fantastic help and I will make use of the links.
Both the RA and decl setting circle rings are very loose and do not have a tensioning screw or any other means of tensioning or fixed into place (other than using lots of glue as there is at least 1 - 2 mm space between mount and setting circle)
I can use the glue option to put them into place, but that will void the warranty.
I'll take it back to the store and get one that does not have that problem.
again many thanks.
