The FilterInfo looks OK now. It is using the correct (luminance) filter for pointing and focusing. Also I note the large pointing error that ACP corrected after the startup autocus:

00:25:18 Doing auto-center...
...
00:25:33 Plate-solve pointing image.

...
00:25:36 Pointing error is 18.238 arcmin @ angle 104.98
00:25:36 True focal length is 2799.3 mm.

The image that ACP could not plate solved was plate solved by Maxim.
Since MaxIm uses PinPoint for solving, this means that your PinPoint settings in MaxIm and ACP are different. The plate scale could be different. The pointing update and first successful final image solve show a real focal length (-> plate scale) of 2799 mm.


Check the focal length you have set in ACP:
