That's right Scott,
Using Param Set 2, uses less in-camera colour manipulation and less sharpening of the image. But even with Param Set 2, the DGIC? processor in the camera still alters the original image data before you get to see it. It would be great is Canon had another Param Set which told the on-board image processor to just give us the image as is without any adjustment - then we'd be able to properly calibrate images and take astrometric measurements from them. Oh well - it's still a value for money astro-imager.
