Would it be possible to add a new focus trigger condition in sequences or mosaic/research and survey?
One of my imaging scopes is an SCT, and it is strongly affected by temperature change, but the focus change lags behind the temperature change, if I trigger focus runs based on temperature delta it was often possible to see the focus continue changing after a focus run, the first exposure after focus would be sharp then the successive ones would go out of focus until the scope stabilised. My only resolution was to focus after every third exposure to keep it in focus early in the night as the air temperature fell, but this obviously leads to lost time repeatedly focusing through the night if the temperature is stable.
Given the image statistics Voyager generates, would it be possible to use percentage HFD change since the last focus run as a trigger? I imagine cloud could fool this measurement, but in that case your data will be poor anyway.
