Just adding a link worth to look at.
Toni, While your panohead shows a nice round circle, the floor is poorly stitched. Something is wrong with either your stitching or the panohead setup.
Thank you John and Heinz for your time and patience helping us newbies.
I will not take more time in this topic and will experience myself taking more shots than asking :-)
I've moved my upper rail just a little and my nadir footprint looks better stitched now without the tripod ghosting and apparently no parallax errors.
Just the easy leveller appears to be not correct, it's not appearing entirely.
Thank you !
