I am trying to test manual dithering. I think, after checking the box manual dithering, Ekos applies dithering with the settings of Dithering option.
I create a sequence of 9 frames of 5 secondes and dithering every 3 frames. At the third frame, Dithering is writed into the Capture tab. But it goes round and round. I can do only one thing, stop the capture.
What' 's wrong ?

As you are using manual dithering, does that mean that you do not use guiding? If so, you still have to make an optical train where you select your mount as 'guider'. In the Ekos Guiding tab you then select that optical train.

There are several people that have experienced the same issue, and this solution did the trick. But again, in these cases the mount was run unguided (10micron). Not sure if that is the same as for your situation.

Thanks. It is OK, doing as you say.

W J DRIJFHOUT this wasn't clear to me at all, thank you. I've created a bug ticket for the missing documentation about this.
