Skywatcher 80mm f/5 achro - outside diameter, please

Hi folks,

I have a GSO refractor focuser that is for an inside diameter tube of 86mm. It came off an 80mm scope, but its objective lens is a very poor one. If I can I'd like to salvage the focuser, putting it onto a better quality Skywatcher achro.

So I would like to know the outside diameter of a Skywatcher 80mm fl400 instrument, please - this way you don't need to remove the focuser to measure the inside diameter.

Many thanks,

Mental.
