I have built from source from Git. I don't seem to get the entry in the FITS header, but I don't know a way to verify If I actually have the right version. KStars itself reports version 3.4.0. in the logs(quoted below). Do you think I have the right version?
Yesterday, I managed to take a few subs between the clouds, and I can confirm, the OFFSET header is there.
