I have been successfully using Ekos polar alignment on mac laptop and am trying to switch to using a Pi running Ubuntu.  Polar alignment is failing on the Pi because plate solving is failing.I did some tests with the camera (EOS R) pointing at the sky and asking Ekos on the Pi to plate solve.  When it failed, quickly switching to the Mac where it succeeded.I have been trying to create a reproducible test case for plate solving using load and slew and am seeing some unexpected behaviour.I have a test image, laptop-3, taken using the laptop.  I used the camera module to capture and store the image as a fits file.  I have three version of the image.  laptop-3.fits captured by the camera module, laptop-3.CR3 - the matching file from the SD card in the camera, and laptop-3-siril.fit.  This last file is laptop-3.CR3 converted to fit format using Siril.I have used load and slew to load and plate solve each of these three files on both the mac and on the pi.  These are the results:Ekos on the Pi does not seem to recognise .CR3 files in the load and slew file selector, so I can't try that option.  Otherwise, it would appear that Ekos cannot solve the fits file recorded by the camera module, but can solve the original .CR3 file from the camera and a conversion of that file to .FIT. format done by Siril.  I do not know whether this behaviour is related to my real issue which is plate solving, and thus polar alignment not working on my Pi.  But maybe.I have attached a log file from the mac attempting 3 solves, first laptop-3.CR3, then laptop-3-siril.fit, then laptop-3.fits.  For the first 2 files, 8 solvers are started and in both cases solver 2 ( "Solver
