Hi.

I was wondering about the focus position in the header as well. The modifications n the indiccd source files listed below (output from diff) appear to make it work for the CCD simulator. To my understanding this should be propagated to any CCD driver. I haven't done any further testing though, so I cannot tell whether this true and whether the mod could mess up other things.... but it at least suggests to me that it should be possible quite easily?

Cheers,

Joachim
