Is this possible ?
I don't have an autofocus setup (yet) so was trying to work out how to use the app to do the capture and HFR measurement.
Is it possible and if so could some kind person tell me how please ?
I'd rather not take a laptop as well just to do the focus using APT.
Thanks

OK so the answer is it's a bit messy.
Something can be done with the focus tab and selecting the left/right button next to the AutoFocus button to simulate liveview, but it's slow to display the image from the camera.

I've gone with a USB OTG cable from the camera to the tablet and run Camera Connect & Control app, then enable live view. When used with the Bahtinov mask that's built in to the WO ZS61 it should work fine.

When the pennies accumulate again then an autofocusser from FLO is in order and I'll use EKOS again for this.
