Yes, I use the mirror lock. I refocus often now. It has made a big difference.
When temperatures are changing, or the OTA is cooling down, I I do it
Other than that, once things stabilize I will still do a touch up every 45
minutes to an hour and with each filter change. I do not have to touch the focus
knob though, just a touch up with the NGF-S

Great-looking image! Do you use a mirror lock on your SCT? How often do you
have to adjust focus during a typical imaging session?
