Hi Thomas, congratulation with your purchase of the ASA 12N and welcome to the forum!
To avoid any differential flexure, Off Axis Guiding works better then a guidescope. That goes for any telescope, not only an ASA.
Especially reflectors, because of the use of the mirrorcell are criticall for differential effects with a guiding scope.
On top of that there will be less weight involved to be carried by your mount.
I don't own an ASA telescope, so I have no idea about backfocus and possibillities for an OAG.
Succes on your decission and the steep learning curve of astrophotography!
