G'dat g__day and gbeal ++,
Preliminary results are somewhat discouraging re the banding.
So far I have:
1. isolated the camera side earth from the puter side earth with no better result.
2. provided extra ferrite suppression to the usb cable. with no better result.
3. changed from tricolor file saves to CR2 saves, with no better result. Interestingly the lines are more evident after RGB conversion though.
4. used bias frame with dark, and also tried scaleing. This seems to have reduced the lines significantly, but with o/cast skies, I'm waiting to give it a good test under actual imaging conditions.
a puzzled,
Doug
