Fred PHD does not offer binning on the guide camera but I will use this when guiding in Maxim.
Flexure is a problem when guiding with a guide scope, not when using the QSI. I had trouble getting the settings right with whilst using the QSI's OAG so I wanted to get away from the problems of flexure that I had with the guide scope and that meant using the OAG, which was not working well with the settings I was originally using and given that clear sky is fleeting I went back to what I knew would work more or less. Yes flexure is irrelevant.
I had to get a spacer because the focus ring on the QSI would not go in far enough to gain focus on the RC8. It works fine on other scopes without the spacer but on this scope I needed to have the spacer so that the focus on the OAG was the same as the main sensor.
