The issue was focusing. The lens is a Canon 200mm macro FD. The camera is a mirrorless M1. The adapter matches the FD to the M1.
The mount is a Ioptron tracker. It was reasonably aligned to CNP using the polar scope and a Polaris position app.
The system appears to focus beyond infinity. Using the 10x feature on the M1 I carefully focused on Deneb at f4. That was touchy, there was a definite halo on Deneb. I then stopped down to f5.6 and proceeded to take 40 50 second images. This was a test, no dark or bias images were used.
The result was actually very impressive for a first try. I stacked the images using siril. There were hot pixel track in the final image.
The M1 worked very well. I am looking for a how to to finish the color processing. The M1 raw image from the original question is answered. Thank you all. Dan
