Focus based on temperature change

Focus based on temperature change was created by Barry Carney

After updating the software on the Pi I notice that the focus module in EKOS now has an option to re-focus based on delta T. Has anyone played with this yet?

I know my EAF has a temperature sensor but have never bothered to monitor the temperature change over the course of an imaging session. Is there some way to plot/trend the temperature? Next session I will have to keep an eye on it.

If your software is up-to-date (or running nightly), see this post:

It will likely help. Cheers, Doug

I'm only running the stable version but I'll have a look for that log file it should be very handy.
