Check the Mac App Store for updates, because we’ve just released Observatory 1.0.8.

It improves the background gradient handling of the plate solver and align adjustment. It also fixes the issue of stacks not being updated after selecting different picks. And we resolved a bug that we believe may have been the cause of thumbnails occasionally shifting down in the image strip browser on macOS Sierra. We have not been able to consistently reproduce this issue though, so if you still see it after this update, then please contact us.

See the release notes for the complete list.
