My understanding is that if you use the refocus option in the Capture module, it will only refocus, NOT align (I haven't used it for a long while though). Like you, I like the scope to re-align now and then, not just to adjust for drift but for minimizing the risks of errors during a long night (at times scope seems to be off target when clouds have passed, for instance). So I set up a series of identical jobs, like 20 or 40 120-180 sec exposures, in the Scheduler. THen it realigns, re-focuses in the beginning of each job (after 20 or 40 exposures, depending on the capture sequence I use).

On the other hand: if the target drifts noticably during focusing, I'd suspect something being wrong - like polar alignment.

Ok, that's a shame. It kinda removes the ability to use the "Refocus if temperature changes" option.

My Polar alignment isn't a problem (usually below 10" error), but I'm using the SEP - Linear focus method which is accurate and reliable but slow. When it's done the target has drifted a little bit. If using some faster focus algorithm and method the target doesn't drift noticably, but I've had some focusing issues with failures and dead locks. No issues (unless clouds appeared) with SEP/Linear. I'd really love a "Realign after focus" option in the Capture module.
