Tips on how to fit the ZWO OAG Off Axis Guider and set up with ASI290mm. Astrophotography guiding PHD2

Introduction to the ZWO OAG off axis guider and ASI290mm mini.
I have an Altair RC8 scope with 1624mm focal length. I was guiding with a scope that was only 240mm with an ASI120mm mini. It worked but would sometimes struggle and my images and stars could look soft. Rule of thumb is you need to have a guide scope that is no less than a 1/4 of the focal length you are imaging at. This would have meant a 400mm guide scope for me. Costly and a lot of extra weight so the best solution was a OAG.
ZWO make a good OAG that comes with all the adapters you may need to fit it. It works well and was not too difficult to set up.

Serious improvements in my guiding. I have gone from 0.8 average total RMS error guiding with a 240mm guide scope and 120mm mini to 0.4 - 0.5 Total rms using the ZWO OAG and the 290mm mini. I can see much more finer detail in my images
