As a long time PTGui user from 2008 or so I have never had this zenit look.

Maybe  it has to do with the altitude of the sun (23° above the horizon) which caused a hard edged flare in one of the photos but it is further away from the zenit so probably no influence.

My normal workflow is export TIF's from Lightroom Classic and import in PTGUI Pro. 
If I export DNG's from Lightroom Classic the resulting panorama show a correct zenit.

The problem is showing in below screenshot of the zenit. I have change almost every setting but the problem still exist (when using TIF's or JPG's).

The supplied jpeg images are overexposed compared to your sample view of the zenith.  No exif data in the jpeg files either.  However, I managed a reasonable stitch with no slightly lighter cross at the zenith.  I got a slightly better result using multiband blending.  (Project file attached).  I would always use 16 bit tiff source files for the cleanest blue skies.  Maybe the size of crop circle is a factor.

Hi,

In your JPEG files (with John's project file) I can't see the issue. So
I would need to have the original images and your project file to
diagnose this.

Since the problem does not happen with your original DNG files, I
suspect it's caused by the settings you used in raw conversion. Don't
apply vignetting correction in Lightroom, PTGui can do this better
because it sees the overlap between images. Don't apply shadow/highlight
correction during raw conversion and use identical settings for all images.

Try switching to Unblended view in the panorama editor, there should be
no color difference between the images if they are developed correctly.

Kind regards,

Hi John and Joost,

The link which is now in the second message are the DNG's. Yesterday I deleted two posts (with the jpg's.).

John,
 I had sent the halfsized jpg's and everything zero in Lightroom Classic (not a good idea because the jpg's were not with my workflow settings). I never work in jpg's but in TIF.
When I change the crop it didn't approved. You didn't find an issue because of the solution I write below. Thanks.

Joost,
I checked the Lightroom Classic settings in Develop and saw that the 'Enable Profile Corrections' setting was ticked. I removed the tick and zenit looks like below screenshot in the PTGui viewer. Much better. I also have not applied Highlights and Shadows during conversion to TIF.
Strange, I didn't had this behaviour earlier with these settings active.

Also the other panorama's of that day showing now a good zenit. Thank you for the help!

Best Regards,
Peter
