It looks like you recorded your exposures around midnight on Oct 3, but the ST4v chart that I posted was for Oct 5 23:54, two days later. Here's the predicted motion from Oct 3-6:
Again from the Bathhurst Observatory. I need to add the location that you posted for the future.
Have you uploaded your image to Astrometr.net? They can plate solve it & ID the MPs detected. I've used it to platesolve some images taken with iTelescopes.
Here's a link to the web based site:

Good luck,

Hi Phil
Thank you for following up, it has given me the opportunity to correct a mistake I have made - the images were indeed taken on 5th Oct and NOT the 3rd Oct.
The original image sets are on my Notebook and when I processed the data and transferred the finished TIF to my Desktop PC, I mistakenly labelled the in-coming Folder as 3/10/2021 and I have therefore carried that Date transcription error forward throughout my posts above.
Having gone back to the source FITs files on the Notebook, I discovered this error and have now overlaid an ST4 Screen capture, as set for 5th Oct 13:00:00 UT, and it EXACTLY places Christophe correctly on the individual Frame exposed at 13:00:00 UT.
Please accept my apologies for this transcription error, in particular to Greg whose SW proved to be accurate and reliable, performing flawlessly, despite my efforts to break it.
Cheers
Dennis
