Yes, you should attach the guider to the imaging scope. I have always recommended that. A separate guide scope on top of the rings will not work because the imaging scope will be flexing inside the rings and be pointing in different directions with gravity.

I am asking because George suggested to me that in order to avoid flexure, I should be doing my guiding with the Baader Vario-Finder attached to the imaging scope rather than to use a separate guide scope piggybacked on top. I already own the separate guide scope and dovetail plates, but I would have to purchase the Baader Vario-Finder. I don't want to buy one if if it is not accurate enough to use with the longer focal length of the 180.
