If you are getting round stars then you are there. I've seen some Honders setup that use the Baader vario finder scope with an AP made special set of rings to attach it.
Roland from AP has said that guide scopes should be attached to the OTA body not the rings. When you think about it the scope could flex slighty with regards to the rings and its the scope you have to match not the rings.
But if you are getting round stars like these guys using the Baader vario finder as a guide scope on the Honders then you are there. If not then this would be something to look at.
