Dietz,
Fantastic news, congrats and its a great looking scope. Another addition to your arsenel of scopes.
I have the Argo-Navis - Siderealtech combo for my G-11 mount, but it will just as easily handle Alt/Az. Also the Sitech can also be driven by just a laptop without need for the ArgoNavis. But for standalone portable use you cant beat the Sitech/ArgoNavis combo.

Also you can get a custom solution from gototelescopes.net who will provide you with a sitech kit for your dob.
