I am a complete newbie with image processing, but I noticed something like that in a moon image I took. I had already aligned, stacked, tuned the .avi, and did not notice the blurring to the left side of the photo (attached) until later. Seems to be an artifict of Registax - when I reprocessed the file the blurrines was gone.

By the way, the amount of coma seems excessive for the MFR-5 on an SCT; are you using any additional spacers?

I am using a 5mm spacer between the camera and the MFR-5. Not sure I understand about re-collimating. If the collimation looks good through an eyepiece wouldn't I be adjusting the telescope to make the camera view better then have to go back for visual?

The addition of the spacer quite likely is worsening the coma/field curvature. If an improvement in off-axis stars results from its removal, I'd recommend dispensing with it; the difference in image scale and working f/ratio is not to great as to miss badly.
