To continue from my previous post I found making the guide scope modification was "more complicated then I thought". I discovered a couple of problems (lucky I did not build anything!!).
Placing stuff under the main scope needs a bit of thought as there has to be clear movement for 360 degree round the declination axis. When going through zenith will anything knock the tripod?
Is the guide scope far enough from the main scope to give about a total adjustment angle in dec of about 20 degrees (10 degrees off centre).
Is the mounting plate rigid enough? Pointing to zenith may increase local imbalance loads and cause the guider mounting plate to flex so much so that the guiding will be off.
Suggestion: 6081 aluminium plate is ideal for this application.
