Manual Focus - How are you doing it?

Can you not use this HFR tool/stat on a single brighter star? I'm too coming from BYEOS, but now have a CCD, I also have no intention of purchasing an auto focuser because I'm generally always outside in the observatory when imaging anyways. The added cost, weight, is not worth it to me. With as great as software can be now, I prefer not to fiddle with a B-mask, I just want to slew to a star, and manual focus while I watch the monitor for the lowest ##. I'm super new to SGP but I'm starting to get the feeling it's not very user friendly to those without a fully automated observatory
