I did not feel super confident that I had recorded the faint outer satellite Leda on the images I took on my second run, posted above, so I went back to Run 01 and processed the 27 x 60 sec frames using PixInsight.
Pleasingly, the results were much more conclusive, and I now feel more confident that I managed to record the faint trail of Leda, a magnitude 20.068 satellite of Jupiter.
I obtained the positional data from the JPL Horizons website and plotted the calculated positions for the start/end times of the 27 frames I captured, and the fit was excellent.

I plotted the JPL data and when I overlay the results in The Sky X Pro, there is a very good fit to the recorded trail.
I also identified some fainter field stars using the GAIA DATA RELEASE 2 (GAIA DR2) Catalogue and annotated the attached image. This has given me more confidence that I now have a good candidate for Leda.
