Hello
I purchased PixInsight last week (Version: 1.8.8-4 Ripley for Windows 7) and am trying to edit some of my color-images taken with a Nikon D850 and a 135mm Rokinon lens. Unfortunately the Photometric Color Calibration process fails on all of them. As an example, in one image I have Deneb pretty much in the center. I do this: First I press “Acquire from image” which returns the focal length, pixel size and date/time in UTC. Then I enter the RA and declination of Deneb as found in Stellarium for that day and time. I leave the defaults for everything else and execute the process.
It does try to find matching stars but fails. During the process I get these messages:
* Previous attempt failed - this is try #31
useScaleDifferences=false
* Target image: Limiting to 32000 brightest stars.
Matching stars: done
856 putative star pair matches.
Performing RANSAC: done
* Previous attempt failed - this is try #32
Etc. etc. etc.
and eventually:
*** Error: Unable to find an initial set of putative star pair matches.
*** Error: The image could not be aligned with the reference star field
Please check the following items:
The initial coordinates should be inside the image.
The initial resolution should be within a factor of 2 from the correct value.
Adjust the star detection sensitivity parameter, so that the script can detect most of the stars in the image without mistaking noise for stars.
The catalog should be matched to the image. Choose the appropriate catalog and magnitude filter, so that the number of stars extracted from the catalog can be similar to the number of stars detected in the image.
*** Error: Unable to plate solve the image: Alignment failed
This is usually because the initial parameters are too far from the real metadata of the image.
** Warning: Process finished with errors:
PCC_T_XVH6L66RNT1A.xisf: The image could not be plate solved
I also tried to look up via Internet and entered NGC7000 (and M42, M51 and M101 in previous tries) – all failed. I get these messages.

I do need to run this process I believe, I have a hard time to get good colors into my image if I skip it. And so the quality is impacted.
Any feedback appreciated.
thanks
