Welcome to SGP!
SGP is very flexible in terms of focusing options. There are many
combinations of what people can do based on their setup. I think what
many people probably do is:
- Calculate filter offsets (once)
- In the Control Panel/Focus tab, choose “Use Auto Focus” and “Auto
adjust focus per filter”
- In Auto Focus settings choose “Auto Focus with filter: LUM” and
"Auto Focus every X degree change".
This means that between exposures if the temperature drops by whatever
degree you have set, SGP will switch to the LUM filter, run auto focus,
calculate the offset for whatever filter is for your next exposure and
move the focuser by that offset, switch to the imaging filter and start
I don’t have a temperature compensating focuser, but if I’m not
mistaken, SGP does not move the focuser during exposures but only in
between exposures. If you want to use temperature compensation so that
the focuser adjusts focus during exposures you will need to use the
software that came with the focuser independent of SGP. Someone please
correct me if I’m wrong about this part.
It will also help to know what equipment you are using.
