Also, I have only used FITS so far, not JPG, and they work for me.

Thanks Don. I did try that, but sounds like it is worth another try! I wonder about the effects of slight cropping which I do around the edges due to minor stacking misalignments (but that doesn’t affect the pixel size or focal length, just image size).

Have you used the "Settings Assistant" on ASPS? It is shown under "Settings", then "Settings Assistant" and will calculate the effective f.l. and pixel size.

On my scope, I used the calculated focal length and this assistant came back with a correction that reduced effective focal length by about 10%. No explanation, but my plate solve now works. Point being, it might not be the image but the settings.
