Re: PHD2 Calibration
I haven't noticed the Guiding Assistant before. I'll have to check it out. Obviously, I can't advise you on it at this point.

Re: PHD2 Calibration
I plug everything in, fire up
My guiding is fairly consistent, though the better I balance the smoother the guiding is. I've even swapping imaging scopes (but used the same guide scope/cam combo). Smoother guiding with my ED80 versus my SV102T (less weight, shorter focal length).
I may try the Guiding Assistant again next time out. Might make things better. I suspect I'll see the same results. But, I don't know much. I haven't been guiding for an especially long time.

Re: PHD2 Calibration
The Guiding Assistant is an instructional tool to help you measure current seeing conditions and the general behavior of your mount and guiding subsystem. When it's run, it temporarily disables guiding output and measures the ensuing motion of the guide star. This can help you see the high-frequency motions caused by seeing (atmospheric) conditions. These cannot be corrected by conventional guiding because they occur at a much higher frequency than you can typically even measure. Trying to correct for them with conventional guiding is often called "chasing the seeing" and usually leads to poor results. Avoiding it is best accomplished by setting a minimum-move level that will cause PHD2 to ignore most of this high-frequency behavior. The Guiding Assistant can also show you other behavior of your system such as overall drift rates in right ascension and declination as well as peak-to-peak and maximum-rate-of-change measurements in right ascension,. While these things can usually be "guided out", measuring them can be helpful if you want to improve the underlying performance of the mount - for example, by improving your polar alignment if the declination drift rate is high. The Guiding Assistant can also measure the declination backlash in your system if you select that option in the user interface.
