I still focus with a bahtinov mask. From refractor to SCT. The FSQ106N and the CN-212 are very sharp and demanding on exact initial focus. The mask is good enough to achieve very good near perfect focus visually. Once you are in focus you need to keep in focus and that's harder.

I used focusmax in the past and spent the time doing V curves or focusing by the numbers with a live view and a FWHM value. It's like polar alignment (provided you can see the SCP). You can get a level, a compass and good polar scope and be done in 30s or you can do drift align or use polemaster or use alignmaster, etc...

In the end, if you're not remote imaging what ever is easiest, usually visually, is the way to do it.
