I used an Orion thin of axis guider with a Canon EOS 60Da and a ZWO ASI 120mm as the guide camera for some time. It worked well, it certainly lead to good tracking. This at a focal length of 2415 mm., PHD2 total guiding rms typically between .3 and .5 arc seconds with reasonable seeing, .7 to 1.0 on poor nights.


The downside is that it is sometimes difficult to find a suitable guide star.
