My last session was an attempt to create a mosaic of 4 panels with 5 subs each. The entire night should have been clear, not 100% sure about that, but the mosaic failed at the exact point that it started on panel 2. This to me sounds like it might be a bug as it's a bit too much of a coincidence. PHD2 reports "star lost", but I think that was because EKOS was slewing, so PHD2 wasn't suspended. Might that be true? Here's part of the log where it goes wrong, right after the completion of panel 1;

Thanks for log. What's odd is that it is missing log when the job completed. I tried to replicate your conditions, but PHD2 was stopped after the first job was complete like it should. Nevertheless, I discovered a few issues with PHD2 support that were not present in case but I stumbled across them so those are fixed now in GIT. More over, the mosaic "drag" feature was not generating correction positions, and I also improved the FOV in case you need to rotate. These are in GIT now and will be available in KStars 2.8.3 release.
