One of these days I'll upgrade to something like a ASI1600MM-cool to go with the filter wheel I've already got, so I can get big-grown-up Ha photos. When that happens I'll be back looking at back focus (not looking forward to it, but I think you need a spacer rather than to shorten it). Just don't suggest an OAG!

See how that goes then Bill, yep, hope it is enough
BTW, what is meant by OAG a) Off Axis Guide 'or' b) On Axis Guide
Apparently On - Axis is the flavour of the month at moment
All the best
