Does look like it was made for the scope. Nice bit of work Brian.
Is it a 'real' 3" focuser...that is can you use a 3" diagonal on it? Or is it a fake one like the GSO's, that as far as I know are 3" but only have a 2" capacity. The one I have the 2" part unscrews leaving threads and a slightly bigger than 3" drawtube with no way of attaching a 3" part, unlesss its avaliable as an addition from somewhere...
