Perhaps I simply didn't explain what I'm referring to correctly. Using the screen grabs that I've posted, if you look at both the Ekos drift plot and the Windows PHD2 drift plot, even though the radius reference limit is set to two arc seconds, the plots both measure out to FOUR arc seconds. The PHD2 drift plot on the Astroberry however ONLY measures out to TWO arc seconds. What I want to know is whether there is a way that you can set the drift plot in PHD2 on the Astroberry to also measure out to four arc seconds, just like it is in the Windows version, while maintaining whatever radius limit that you've set, which in these examples is two arc seconds. Is that clearer?

Also, when you've assigned PHD2 as your guider in Ekos instead of the internal guider, when you start guiding in the Ekos guide module, the main time-based plot is echoed through into Ekos from PHD2, is the drift plot data also echoed to the drift plot in the Ekos guide module?

Thanks.
