Thanks Andrew, Frank, Rich and Eric! I`m quiet happy with the scope for its size!
Rich, the tube was rolled and welded locally out of 1.7mm aluminium. They did a rather crappy job of it, had to take it back and make them straighten it out twice and took alot of work to get it close to round and smooth. I shall find someone that specializes in this sort of thing next time. But have to admit its solid!!!
Try to update my website soon, its rather time consuming and finding spare time gets hard sometimes...all a learning experience..but getting there...

Cheers and thanks everyone..
Gary
