Thank you for your response to the OP question. Your response reminded me of a question I have had for some time. I often hear the advice to avoid mounting a Guide Scope using rings and to mount the guide scope directly to the primary instrument to avoid flexure issues. What is not as clear to me is how to mount a guide scope other than small finder scopes to the primary instrument without using rings?
I have a TEC 140 equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser which has mounting holes for a small guide/finder scope. I currently use the 10×60 Baader Vario scope with the AP 10 x 60 Quick Release Guider Bracket (1060VGKIT). Which is all well and good as long as I stick with a small light weight finder/guide scope like the 10 x 60 Baader Vario scope. However, if I wanted to use something larger, like an 80mm scope for guiding, how can this be mounted directly to the primary instrument without using rings? I have just always been curious as to what mounting options you have if you want to use a larger guide scope and still avoid using rings. It maybe that the side-by-side mounting option being discussed in this thread is the only option, but just wanted to confirm.
