I am using an Optec Direct Sync ACF focuser with a FocusLynx controller. It seems when using the temperature compensation feature the focuser is trying to follow the temperture drop using the hundreds of degree change instead of tenths. I have confirmed with Optec that their temp probe isn’t that sensitive, and the FocusLynx controller algorythm is also using only tenths of a degree. The focuser does change a small number of steps with hundreds of degree change, but after about 40 minutes the focus isn’t as crisp anymore. I have to run a auto-focus routine, then it seem to track ok again for a while. I believe I have the temperature compensation value set correct, I used the data from two nights of doing the auto-focus about every 10 minutes. Since Optec says both the temp probe and the controller is using only tenths of a degree moving in hundreds has to be coming from SGP. I believe the focuser trying to follow such small temperature changes when it’s not that accurate is inducing errors into the routine. Is there a way to have SGP track the temp change and move the focuser only following tenths of a degree not hundreds?
