Temperature and filter offsets.
Is it worth it?
Sure you can take your nominal focus and subtract the temperature compensation and adjust for filter offsets, or you could just you know, run a v-curve and actually look at what's going on.
Put it this way. I would feel uncomfortable relying only on temp and filter offsets to determine critical focus. And if you're going to do a V-curve anyway, why bother calculatng the offsets in the first place?
Am I missing something here?
