That's what I've been doing now manually, but of course with this approach you get vibrations and movement as you make adjustments. This can of course make it tricky to get the best possible FHWM value. The best that I'm able to achieve is between 5-7 FHWM (but will usually average between 9-12) when zoomed in at 10x using APT's focus tool. At actual pixels It's about 2-3 FHWM. Which seems to look OK to me when I take pics.
