following the git log of INDI commit 7666cfe395... has added this feature to INDI. I've compiled everything from git yesterday (both INDI and kstars), but still have no entry in the FITS headers. Do I have to do more than having the focuser (mine is a Pegasus DMFC) listed as Snoop Device in the camera settings (ASI1600)?
Is this working for you, and if so - what setup?
