Star Adventurer Mini Modification for Guiding Scope

It was desired mount a guide scope with ASI camera on a Star Adventurer
Mini SAM mount. The SAM and guide scope will be used with an ASIAIR
mini computer to control and guide the RA movements of the SAM, thus
providing longer exposure time. This video describes a DIY project to modify the Dec L-bracket to allow this. The Dec screw was modified to hold an additional aluminum attachment plate for the guide scope. This also allows use of a large main scope with attached camera.

I realize that the SAmini does not have a guiding feature. However the SA2i does and the same modification shown here would apply.
