Hi David,

This is the option to check to save the focus images...

Would be helpful so see some images of the v-curve. In order to focus you need to defocus enough to get a decent v-curve but not too much so that the stars disappear or deform so much as to give false readings. Its not possible to say how much this is, that would cover all the equipment possibilities, so you have to experiment.

I'm not aware of documentation for the simulators unfortunately so you have to play around or look at the code. You can for example, replay focus images previously stored in order to test out different star detection parameters.

Good luck!
