Dithering Checkbox in EKOS - by: JustMakeIt

Sorry for my very newby question, but I'm not able to find the checkbox that should enable dithering in the Ekos guide panel, as explained in the Ekos manual : indilib.org/about/ekos/guide-module.html

Where is it ?

My setup : QHY5II as guide camera with on-camera connection to the scope ( it guides just fine ) and CCD simulator as acquisition camera.

Thanks !
